  1. Note that the AC has a wire to the ECU to tell the ECU its running, this ups the idle by about 100 rpm
  2. A standard warn 8274 has an overload safety cut out system I seem to remember, the free spool handle pops out when a certain load is reached (it does not go it to free spool when under load though) A lot of people with this winch drill and R clip the handle to stop it popping out) When I bought my 90 it had a bank of self reseting fuses to protect from overload (each 50A with 5 in total, but this is only half load of the winch ) It was soon removed.
  3. I used http://www.euroweb.uk.com/ They custom made them for me (no extra charge) as I wanted them 5m in length and with clip hooks (I don't like the claw hook type)
  4. I know somebody who has just had to have a new clutch pack and torque converter in a hp22/24 hybrid box and it was connected to a 2.8 tgv
  5. Having ready the proposed new MSA rules 58.2.4. All vehicles must be fitted with a circuit breaker which isolates the battery from all electrical circuits, which simultaneously stops the engine and which is operable by the driver whilst correctly seated. K.8 recommended And section K8 of current blue book says nothing about current rating or method of isolation. I'm no MSA scrutineer but as long as your winch does not when then main isolator is off then you should be ok (so make sure the solenoids are powered via the main isolator not any additional isolator) This is the way Boothy and myself do it. Note that I don't think that factory standard Warn or Superwinches (and possibly others) will comply as they usually take the solenoid power from the main winch power cable but that can easily be fixed.
  6. My example of a albright DC88P is bad, as it's not a cut-off switch but I could not find the break current of the large durite isolator, but as the durite isolator has a thermal current rating of 250 to 2500A I would expect it's break current to be at least 2500A. As for people using the albright DC88P, most people I've seen uses these as the control solenoid for their winches (usually 1 per motor). And using these the winch motors are isolated from the battery by default (I would still use a manual isolator as well) Warn and other Winch manufacturers ship winches with similar rated control solenoids (and some even sell them as extra cut-off solenoids) As for the MSA trying to specify things like current rating etc, they should not bother and just ban winches As most winch manufacturers (warn, superwinch, etc) ship their winches with 2 AWG or 35sqmm cable, Depending on your info source that size wire is on rated for 95 to 240 Amps No way near the current rating they quote for their motors of around 480Amps (or they are lying about the HP of their motors)
  7. Now is that the appropriate break current rating or thermal current rating? As it is to isolate the electrical circuits then I would use the break current rating (on a DC88P albright this is 800A instead of the 100Amp to 180Amp thermal current rating)
  8. I don't know what is "new" for 2011, but the regs have always said isolators to cut of all electrical power including winches, but most people do this with multiple isolators. So I would use from VWP or other places. Ref: BISALP to cut off engine and main car electrics, protecting the alternator Then one of Ref 60550 for each winch. I also make sure that the albright solenoids are powered from the main car electrics, so that cutting the main car electrics also switches the winches off(the Ref 60550 isolators are an alternative and or backup isolator for the winches)
  9. Yes and 2 70sq mm cables are better than one 140sq mm cable (70sq mm circumference is 30mm vs 42mm for 140sq mm), so there is more area to conduct away heat. But multi core, ducting, ambient temperature and bundling cables together affect the current rating as most are quoted as in free air current carrying capacity. What also helps is the melting point of the insulation, as a higher temperature allows a bigger thermal gradient and thus more heat is transferred away.
  10. If you are really stuck there is an easy way to help without increasing the strain on motors, wiring, battery, rope, etc. That is to do a double line pull (then you just need to be worried about what your pulling against )
  11. Actually the lowest rating link in the winch wiring is the solenoid. The AlBright DC88P sold by places like Devon, Gigglepin, etc is only rated to 100Amp continous (http://www.albrightinternational.com/lang/en/products.php?ID=587) Even the Extra Duty version (L model number for Large Contact tips just increases the life not the current rating) The biggest albright you can get handles only 400A continuous but that weighs in at 3.4Kg as is not Protected (P model number) to IP66 standard It is also more common for the albright's to stop working, which is why I carry 2 spares. (they also tend to weld themselves ON, which is where the easy to reach cut-off switch comes handy )
  12. It depends on the motor and efficiencies (74 amps per horsepower at 10 volts) But Warn quote 480Amps at full load (http://www.warn.com/truck/winches/95xp_winch.shtml) for their XP motor. So there is no realistic way isolate or cable a twin motor winch for full load continuously (you would need about a 300sq mm conductor and 4 isolators ) So what happens if you run a cable or cut-off switch above it's continuous current rating capacity, it heats up to above the melting point of the insulation, but this takes time and depends on many factors (e.g. current temperature of the conductor, load, etc) I have melted one of these 250A/2500A for 5 seconds cut-off switches using a twin motor XP winch, but then the contacts stopped connecting. I've not had a problem with my 70sq mm cable (which is rated to 485Amps) on my twin motor setups. Also note that a twin motor winch won't necessarily draw more power (with the same gearing) than a single motor winch, as the power require is proportional to how stuck you are So be mindful of how hard and long you run your electric winch.
  13. Having an ANR1808 in front of me, the Engine mounts are:- metal disc | rubber | metal disc | rubber | metal disc The transmission mounts are:- metal disc | rubber | metal disc And from memory the Transmission mounts offer slightly more flex, but I still rip either type from the mountings as my engine tries to escape
  14. I second that, get a new one. A lot of recons have been recon'd so many times that I found that they don't last very long. Then when it finally goes, get your one recon'd so you know that it is on it's first recon.
  15. I had a brilliant and fun day, many thanks to Paul, Lucy and everybody else especially my co-driver Dom and my brother. My sprained ankle just about held up, I just wish it was as easy to fix as the broken brake light and pop'd rear quarter glass on my truck
  16. How about a hydraulic motor to drive the aircon compressor :-)
  17. I seem to remember that's been discussed before, and it is a big costly change due to things like different crank lengths.
  18. I had also thought of the same thing for Symbian and thought about the USB angle. You might find that RS232 to Bluetooth is cheaper (a quick search suggest about £32 for a bluetooth to RS232) and I would say that bluetooth is probably more suited to WiFi as it will be lower power as you don't really need the range that Wifi tends to have over bluetooth.
  19. Also usually Land Rover tweak any engines they borrow to improve oil delivery at extreme angles and a challenge truck will do extreme angles, so probably not good to get a non Land Rover engine.
  20. The iphone is not very good at multi tasking, so you probably won't be able to listen to Music and get SatNav directions and Log you MS Data at the same time.
  21. I don't think Android supports USB OTG (On The Go), therefore it can only be a slave device. There are some Nokia devices (as well as a few other devices include a Texas Instruments Graphic calculator) that support USB OTG which allows them to be USB masters and do things more like a PC i.e. support other, slaves like pen drives, keyboards, mice and may be even the USB for MS.
  22. Warn quote 480Amps for a 9500lbs pull from an xp motor, so for a twin motor it could reach twice that but would probably not be at twice the load due to different gearing.
  23. The original post did say it was for a winch and some for some winches the theoretical max load would be 1000A (then you can times that by 2 for front and rear winches and yes I have used both at once)
