I have some new information on this. I bought 2 new Battery Tender 800s, one for each battery. They have 3 stages, bulk, absorbtion, and float. The charger's LED goes from red to flashing green to solid green as the battery is topped off. After driving my M1010, when I plug in the chargers...

I've run Plan B for 12K miles so far. If I had it to do over again, I'd go with 2 12V alternators. The 24V alternator rebuild kit is $650 just for the parts! It's also hard on belts. Some say the 12V and 24V voltage regulators will confuse each other in the Plan B configuration, and not...

Right. I got lead/acid batteries. I wasn't sure I'd be able to get the M1010 charging system to correctly handle any other battery technology. I'm having enough trouble getting it to handle the lead/acid batteries for which it was designed. There are alternators and voltage regulators out...

I should mention that I'm having my M1010 alternator work done by a professional mechanic who is very familiar with CUCVs and their electrical systems. I understand this stuff well enough to have a healthy respect for how much damage one can do if you wire up big batteries and alternators...

No. The CUCV power system has 2 batteries wired in series for 24V, plus it draws 12V from between those 2 batteries. So it has both 12 and 24V. When you open the hood, the battery nearer the front is connected to ground and the other battery, so the battery further back has 24v between it's...

I understand that this mod has been working for folks. I'm enough of an engineering geek that I wanted to understand *why*. I may be wrong, but I think I now understand why the DUVAC killed batteries and alternators, why the Plan B Mod works so well, and why it doesn't cause problems. I tried...

I got the answer from an engineer at a major US battery manufacturer. Here is my not-brief-enough summary, for those who might have the same question I had. For the experts out there, if I misunderstood something and there is an error in this post, please let me know and I'll fix it. Assuming...

I have a question about the plan B mod. Say you do something stupid like leave the headlights on and deplete the front battery. If you jump the truck and start it, you now have 2 alternators pumping out as much as 260 amps (160 from 12V plus 100 from 24V) trying to get the voltage up to 14.5...
