mmgemini Posted January 16, 2006 Share Posted January 16, 2006 What size cable are people fitting to 100amp alternators ???From the alternator to the starter/battery. Where are you getting it from?? Are there any really heavy duty ring connectors that will fit the 6mmstud on the alternator. Nothing in VWP is heavy enough. I've fried mine.I suspect the running of the fridge in 65 deg ambiant could have something to do with it. I eat rat poison mike I can cause trouble in an empty house !!!!

FridgeFreezer Posted January 16, 2006 Share Posted January 16, 2006 10mmsq, I (ahem) found it at work you should be able to get something that size from VWP as starter cable, pick something with decent capacity and you can jump-start from your alternator terminal handy if the battery is under the seat VWP code 37090 (170A) will do nicely.

Guest diesel_jim Posted January 16, 2006 Share Posted January 16, 2006 On all my alternator/twin batteries/winch setups i've done in the past, i always use 35mm2 (thats supposede to read mm squared!) multi strand cable. it's like arc welding cable, and about the same diameter (slightly bigger) than the starter motor cables on LR's. you can get various crimp on lugs, down to 35-6 (35mm cable, 6mm diameter hole in the end for the terminal) Quote Link to comment Share on other sites More sharing options...
Les Brock Posted January 16, 2006 Share Posted January 16, 2006 35mm' for me as well, double insulated TQ cable, bluddy hundreds of strand and as flexable as you like Quote Link to comment Share on other sites More sharing options...
minivin Posted January 16, 2006 Share Posted January 16, 2006 Some Nyvin or Raychem 55A cable would do the job (the latter being good upto 135^oC) Raychem 55 6 gauge comes out at 100Amps~, however for a decent safety margin 4 gauge gives you 140Amps~ If you ask for a sample they should be able to supply a metre or two Quote Link to comment Share on other sites More sharing options...
Steve Hiatt Posted January 16, 2006 Share Posted January 16, 2006 I used 25mm sq. I used a jump lead someone had thrown out, cut to length and then got the right ring terminals crimped on at an auto electric place for a couple of quid.

istruggle2gate11 Posted January 16, 2006 Share Posted January 16, 2006 thats supposede to read mm squared! The only contribution I can add to this post (its not much and almost off topic) is...... For the square symbol i.e. mm sqaure use keystroke alt+0178 will produce ² i.e. = mm² (hold down the ALT then use the right hand keypad and type 0178) If you browse windows character map, you will see plenty of symbols, these ones I remember in my head... Diameter ø = alt+0248 Squared ² = alt+0178 Cubed ³ = alt+0179 Degrees ° = alt+0176 Quarter ¼ = alt+0188 Half ½ = alt+0189 Three Quarter ¾ = alt+0190 They work with most "normal" fonts (I do have an excuse, Im a Drafty by trade and early cad systems needed them typing in, not selectable like the modern cad programs) Rog Quote Link to comment Share on other sites More sharing options...

As for the cable size, I use 8ga, don't know what that equates to in mm² Are you guys really using 35mm² cable for the line from the alternator to the battery? Or is that from the starter to the battery? Quote Link to comment Share on other sites More sharing options...

Or is that from the starter to the battery? I think that 35mm^2 is approx AWG 3 (3ga). Cheers, Andrew. Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted January 17, 2006 Share Posted January 17, 2006 Are you guys really using 35mm² cable for the line from the alternator to the battery? Or is that from the starter to the battery? Yeah, i use it everywhere. if you're going to run it from the battery to the winch, you might as well run it from the alternator to the battery, so there is no "weak link" in the charging circuit.

Les Brock Posted January 17, 2006 Share Posted January 17, 2006 Yep... Alternator to the battery, joys of being a Sparky, cable that just needs using , my winch is wired in 2x35mm in parallel...so 70mm total.. no loss of voltage there then Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted January 17, 2006 Share Posted January 17, 2006 I'm using 0.2mm² wire for my winch, it'll pull the vehicle with all the wheels locked - am I doing something wrong? Quote Link to comment Share on other sites More sharing options...

landrover598 Posted January 17, 2006 Share Posted January 17, 2006 whilst were are on the subject of big wires can the earth for a winch and york connector (for jump leads) be bolted straight to chassis like the starter, or do i have to run an earth wire back to the battery ?

Dave, I wired all my -Ve's back to the battery in cable(big), guranteed no duff connections/corrosion or resistance Quote Link to comment Share on other sites More sharing options...
