Update: took the 24v alt to a an alternator shop and it came back good. Put it back in and I’m seeing 14 volts at the top 12v alt and 26ish from the 24v alt. Is this the correct voltage or should I be seeing it closer to 28v when on at the lower alt? Thanks

thanks for the heads up. I’m aware of glowplug and starter changes I will also need to make. The previous owner included a new 12V starter he had purchased when he planned to convert it himself. I pulled the 24v alt today. I’m hoping to keep this fix as simple as possible. If I can reasonable...

update: tested the alts looks like the 24V alt is failing. Need to recheck all connections but looks like I’ll be making the move to full 12v. Thank you to people who helped

tHank you! I’m currently reading through the plan B thread to try to get an understanding of how my ambulance was rewired. I will be tracing wire and checking voltages tonight. It’s a slow process for me. My electrical knowledge is limited but I’m learning a lot thanks to this forum. I’ll report...

yeah they were basically new but looks like I’ll just upgrade to newer higher rated batteries. Good to know about the heater. I’ll probably be selling my current one when I make the switch to full 12V if anyone in SoCal is interested.

Batteries are newer and I honestly don’t know if it was already damaged when I bought the truck. Regardless I’ll be upgrading both at once And processing from there. Thanks for the input

ah I see. I’ll check the alts. And proceed from there. Currently the AC does not work but the heater does which is why I’m torn but I will most likely just complete the full 12V conversion if the bottom alt is not producing 28V. The seller included a new 12V starter so I already have that brand...

thanks for the reply. Was hoping new batteries would be an easy fix. When I bought it the seller tested the batteries for me and the front was at 12ish volts and the rear at 24V but I’ll recheck them. Definitely some sort of hybrid system. I’m torn on whether to do the full 12V but looks like it...

Hello, been lurking for a while and finally decided it’s time to participate, and hopefully get some help. I’ve just purchased a 1984 m1010 with 8k miles on the odometer. It fires right up and runs great. It was owned by a police department and the rear box was well kept. Unfortunately it has a...
