The M series Alternator requires an exciter charge to make it produce electricity. This means it is always draining your batteries through the alternator unless you have a cutoff switch through (recommended negative) ground side of the batteries.
The VRC radios may also cause drain if something is bad, or they provide a bypass in the grounding circuit from the battery to the chassis bypassing your cutoff switch, (i.e. hook them into the cutoff switch as well) but it's the alternator that is pulling them down ever so slowly.

National Guard had this problem specifically as they would only meet every 30 days and many vehicles had to be slaved off (jumped) to recharge the batteries. Solution (late 1990's) was a "Solargizer" (brand name they bought) which is a small solar panel to be hard mounted on the vehicle hood area and trickle charge module to top off the batteries in 12-24V capacity keeping them ready.

If you start your MUTT every two weeks, three max, it should:
a) flush out the bad Ethanol sludge about to lock up the carb.
b) re-charge the batteries so she can sit till next startup.

Any longer than 3 weeks is basically creating more maintenance for you and you (me too... :oops: ) might as well drain the fuel tank, run the engine till the carb runs out of fuel and disconnect the batteries to save on repair costs.

Not a bad investment, my buddy has his set up through the slave connection, it takes about 5 seconds to plug up. I found if you use a 50/50 mix av-gas(100ll) and premium non ethanol(93), it will still crank after a year or two.

Thanks for the recommendations. Ma Deuce has a battery cutoff switch and key nicely mounted through the battery box facing the driver. I also have a 24v battery charger/tender using a quick disconnect that I use. Always use non-ethanol fuel and SeaFoam when necessary. Only way to go.

Nice ride.....I have not seen chargers/maintainers that cheap. Most run $79-$99. I would get a really good one since it will be running unattended. Good luck,

I remember your rebuild, very nicely done, I bought the Battery Tender 2.5amp, it's about 6 yrs. old and still works fine. Seems like it was about $89 back then. Hambone
