Grant. Posted November 6, 2008 Share Posted November 6, 2008 Hi all, This may sound crazy but you never know..... Has anybody ever seen or even fitted, a 240 generator to a defender engine? I was speaking to someone who had seen one retrofitted to a defender and worked off a pulley on the front of the engine so when the engine was running you had 240v Has anybody seen this done, anybody done it and has anybody got any piccis if you have? Thanks Quote Link to comment Share on other sites More sharing options...
landmannnn Posted November 6, 2008 Share Posted November 6, 2008 It was an optional extra back in 50's. (pto instead of pulley) Not a crazy idea, just an old one. Quote Link to comment Share on other sites More sharing options...
TJ101 Posted November 6, 2008 Share Posted November 6, 2008 Nick (rougevogue) has a AC generator set on his vehicle,, 110v IIRC,, Impressive to watch him weld up a track arm at the bottom of a river bed at 7 Sisters , then drive it out Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted November 6, 2008 Share Posted November 6, 2008 It can be a standard factory fitment from SVO, it looks like a big military 24v generator. not sure if you can have both 240 and 110, or only one of each, but certainly do-able. IIRC the camel workshop unit might have had one as well. Lots here for 240v and here for 110v Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 6, 2008 Share Posted November 6, 2008 We picked one up from Sodbury a few years back, bolts to a 300TDi and has an in-car inverter unit (Electrolux) that provides power when the engine's off. Came from a camper conversion, cost squillions new. You can make a normal alternator put out an (unregulated) 110v fairly easily. Or you could buy a 240V alternator (one half of a petrol powered generator) and graft it on. Most are 110/240 switchable. Quote Link to comment Share on other sites More sharing options...
pete3000 Posted November 7, 2008 Share Posted November 7, 2008 machine mart sell the alternator bit, at a hefty price. Note you will want the 1500rpm models though unless you can maintain 3000rpm on the shaft of the alternator with pulley diameter or engine revs. Most of the portable gensets run at 3000rpm though. The southern electric landy's used to have pto generators which ran off transfer box, engaged on lever. This is much safer as you can turn the output off. I'm not sure I would want to run a 240v alternator belt driven off the engine whilst wading, unless you wanted to get a shock and go fishing at the same time. You would need to remove the belt when not required or find a way to stop the alternator rotating. Pete Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 7, 2008 Share Posted November 7, 2008 The southern electric landy's used to have pto generators which ran off transfer box, engaged on lever. I've got one of those setups - mine came with a hydro winch, the PTO pump powers the winch and then there's a generator with a hydraulic motor that plugs in to the AUX point on the front bumper. Pity it's 110v only, must find another alternator for it. Quote Link to comment Share on other sites More sharing options...

Retroanaconda Posted November 7, 2008 Share Posted November 7, 2008 Surely though more volts = less amps, and vice versa? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 7, 2008 Share Posted November 7, 2008 Yes, but the power is the same (110v 10A ~= 240v 5A). I've checked with the guys that made the alternator and it can't be made 240v ho hum, just have to wire a site transformer backwards or such like Quote Link to comment Share on other sites More sharing options...
Philip Tonkin Posted November 7, 2008 Share Posted November 7, 2008 The obvious advantage to an alternator rectified to a DC output is it's lack of reliance on synchronous speed. To use a 240v alternators AC output would need the engine to be governed at a speed that will give 50hz (i.e. 3000rpm, 1500rpm, 750rpm and others in between requiring more complicated pole and less common pole arrangements) The obvious place under the engine bay for this in place of the aircon pump. Some ex-utilities defenders have one, usually accompanied by a hand throttle to ensure the load does not stall the engine. I can only remember these on 300tdi though.

simonr Posted July 12, 2015 Share Posted July 12, 2015 Me! I bought a 4.7kva 230v Alternator - sold as a spare part for a Generator. I mounted it on the same place as the AC compressor on a 200Tdi with some bracketry. My reason was we had very frequent power cuts and the Land Rover running was quieter than my generator. With 4.7kva I could run the whole house without worrying too much. It was driven from the crank idler pulley by a single 13mm V belt. Unfortunately this proved a problem! If you drew any more than 1kw from the generator - the drive belt started getting hot. At 3.5kw it would catch fire - which looked good but wasn't all that helpful! The only way I could run full power was to leave the hose pointing at it! I added a 7V PolyVee pulley to each as a replacement. With this it would run OK up to about 3.5kw - but at 4.7, it was on fire! Still 3.5kw was enough to run the kettle OR the cooker which was OK. I can't remember what I did with the Alternator - I have a feeling it and the mounting kit went to someone on LR4x4. If you are going to do this, make sure the alternator is designed to run at 1800rpm, not 3000rpm (two common options). When X-Eng came along, I needed a Generator & bought a super-silenced 3kva Kipor generator - which was althgether a better option. More protable, didn't catch fire and cost less to run. Sorry!

ChrisB Posted August 4, 2015 Share Posted August 4, 2015 Simon's alternator is in my garage :-) Simon sold it to me with half the mounting bracket attached, but it would be easy to make the other half again. I never got round to installing it on my 200Tdi - good job really as it rolled on the M20 at 65mph! The 300tdi has A/C, so options are limited, apart from a mighty power bulge in the bonnet and a sturdy frame to mount the alternator on top of the engine. I can't ditch the A/C as the WAF is borderline already. I occasionally wonder about powering it from a PTO hydraulic drive, but never get further than a thought. I need to empty the garage so it can be rebuilt with bedrooms on top, so I guess it's for sale too. Chris Quote Link to comment Share on other sites More sharing options...
