harleybaird Posted October 6, 2010 Share Posted October 6, 2010 Hi, when i got it delivered, we had to jumpstart it, we got it going and removed the cable, we then lowered the revs just until the warning light went on, then it cut out, suspecting the batteries were well dead we changed them over to a couple of car batteries. We then jumpstarted it again as these batteries were off our van, after that we removed the cable again and proceeded to lower the revs again just until the light came on, this was about 1500 rpm, very high if you want to remove it off the low loader backwards. after running it for a bit we noticed that the relays were clicking in coincidence with the light, revs still at 1500 rpm. Is it normal to keep having the light come on, what does the light exactly mean, that the revs are too low to maintain a charge?

andym Posted October 6, 2010 Share Posted October 6, 2010 (edited) If you mean the warning light on the driver's panel, the one on my 432 is never on once the engine is running, regardless of rpm. It's supposed to extinguish once the generators reach charging voltage and that should be at any engine speed over 600rpm. I suspect you've either got very flat batteries or a rectifier/control box problem - is the ammeter showing any charge? If you've got a voltmeter, check the voltage across the batteries with the the engine running, it should be 28.5V +/- 0.5V.

harleybaird Posted October 6, 2010 Author Share Posted October 6, 2010 Hi, yeah i do mean the light on that panel, sounding like an expensive fix, um as far as i can remember it was showing a few amps on it but not much.

Tony B Posted October 6, 2010 Share Posted October 6, 2010 Have you checked all the drive belts are correct tension? Connections clean and tight? Quote Link to comment Share on other sites More sharing options...
harleybaird Posted October 6, 2010 Author Share Posted October 6, 2010 Hi, well i couldnt hear any squealing etc, but il whip off the covers to check though. Many thanks Harley Quote Link to comment Share on other sites More sharing options...
sirhc Posted October 6, 2010 Share Posted October 6, 2010 Have you checked all the drive belts are correct tension? Connections clean and tight? There are no belts on an FV430 pack. Quote Link to comment Share on other sites More sharing options...
Tony B Posted October 6, 2010 Share Posted October 6, 2010 (edited) Then having cleared one of the 'usual suspects'. Dirty or loose connections? And of course, all the earths. Have you a decent battery tester, if not worth taking the old ones out and getting them checked.

harleybaird Posted October 6, 2010 Author Share Posted October 6, 2010 Hi, well ill have a look when i get down there, but is it common for the alternators to fail? Many thanks Harley Quote Link to comment Share on other sites More sharing options...
andym Posted October 6, 2010 Share Posted October 6, 2010 Hi,well ill have a look when i get down there, but is it common for the alternators to fail? I think the alternators themselves are pretty bomb-proof, it's the gubbins around them that causes occasional problems. Check the voltage as suggested above to see what's happening. It's worth unmating and re-mating the connectors on the control boxes to the right of the driver's seat (with engine stopped and master switch off!) in case it's just grot in the connectors.

sharky Posted October 6, 2010 Share Posted October 6, 2010 harley , gimme a p.m i'll pass you my number could be one of several things no panic tho could be an easy fix easier to explain on phone tho Iain Quote Link to comment Share on other sites More sharing options...
Diesel demon Posted December 26, 2010 Share Posted December 26, 2010 Guys Did you get this sorted? I have the same issue, the red generator light is lit I have just put a new pack in The batteries are 100% I have checked the leads to the alternator control box Iain has double checked the leads from the engine Now what?

andym Posted December 27, 2010 Share Posted December 27, 2010 Paul - I think my previous reply to this vanished in the ether ... Are you saying it was OK before you changed the pack? If so, it sounds like the new pack has a duff alternator or the rectifier stack in the oil tank is shot. What voltage have you got across the batteries when the engine is running?
