First off, Electric over Hydraulic Plows are electrical vampires. Is your spreader electrical too? I doubt it, but I had to ask. The more you run it, the more it drains the trucks electrical system. Everything under the hood, Automatic Transmission, etc. is electrical and with low voltage go crazy.

I know the plows can be battery suckers, but batts are new and so is the alternator. The spreader isn't electric, i was going to go electric, and im glad now i didn't.
Speaking of the spreader, i've got an idea that i want validated.
The Sander uses a 10hp pony motor to run the unit, and usually is run off a self-contained battery on the side. Alot of guys i know delete the battery on the unit because it's unreliable, and they run power straight back from their own batteries.
So me being a follower......I ran a circut breaker off my passenger side battery, and from there ran heavy gauge jumper cables back to the sander in my chassis. I used one wire to ground right to the battery, the other i grabbed juice off the circut breaker. I then used a tow truck set of jumper plugs, one on the sander and one on the truck side wiring.
Works great, never has a dead battery, so the sander always starts.
Now that i have that explained, my theory: The pony motor has a alternator built in to charge its self contained battery right? well even though i deleted the battery, its still pumping juice. SO..............Yesterday i popped the breaker and started the sander, while it was running i voltage tested the cable, and the unit was backfeeding my power cable with 6.5-7 volts. Is this an issue? Could i have overcharged the system and fried the IDM?
Just a thought. School me oh knowledgable guru's.
Many thanks.
