after talking with doghead on the phone last night, and with a little explaining on his part, I went back out and tested Gen2 again, and it is indeed bad. My thinking was that the system had to be grounded to the chassis, all other systems I've ever dealt with are. But seems I have run into...

Doghead, what is the out put of Gen#2? I'm getting 28 volts or so, how can that alt charge a 12v battery? I'm not trying to be difficult, I'm trying to learn how the system works. You have power from Gen1 going in at say 14.5 volts, Gen 2 picks this up and adds to it, producing 28 volts or so...

Well, I'll get back on it tomorrow, I've mess with it till I'm completely perplexed today, I do understand now the the reading I was getting on the back of alt #2 was the input from alt #1 and that the other wires coming off the back was at 28V. I understand how there getting the 28V, but if you...

well I have cleaned all the terminals, tested continuity on all the wires, chased all the wires down and made sure nothing was broken or disconnected, positive buss bar has a good 28-30 volts, small wire coming into the negative side of #2 battery has 14.5, still I can't get #2 battery to show...

OK, I have check all the connections, I'm getting 28-30 volts to the buss bar when running, on the wiring diagram there is a suppressor between the negative bar and the positive bar. my suppressor has the end broken off, will that keep battery 2 from charging? Edit: I repaired the end and...

OK, several have said I need to rebuild the alternator, While checking wiring is on my list of things to get done today, let me explain further about my problem and then tell me if you still think I need to rebuld alternator, Gen 2 is showing 14.6 volts when running, Battery is showing 12.7 when...

I found a wiring diagram in the stickies, I'm gonna start chasing wires tomorrow, hopefully I'll get to the bottom of it, I did read something about 2 differant bulbs in gen1 and gen 2 lights, if someone had put the same bulb in both would that make the gen2 light a very dim light?

I don't quite understand what your saying, how can it charge and draw at the same time?

OK checked batteries today, front battery is showing 14.6, rear battery is showing 12.7, seems I'm loosing juice between the pass side alt and the rear battery, I did recheck both alts, drivers side 14.8 passenger side 14.6, I checked the bottom fuse, its was not blown, I cleaned it and put it...

Ok, got 2nd battery charged and did a load test with a VAT 40, battery tested well, I'll check each battery voltage tomorrow sometime, were starting to get bad weather here, seems we just aren't made for snow down here in Alabama!!! I'm reading thur the stickies now, I somewhat understand how...

Not know exactly how the 24 volt system works, can the voltage be checked at each Battery? I know that might sound like a stupid question. Last time it did this I charged the battery and had it load tested and it tested good. I have the low battery on the charger now, and the other tested good...

ok, I know I have read about this on here somewhere before, but can't seem to find it right now. my M1009, the Gen 2 light glows slightly, and ever so often I have to put the charger on the back battery. I have check output on both alternators, left side 14.8, right side 14.6, should be more...
