Will Slave Cable Start a CUCV Without Batteries?

[tgtaylor64]

I have an M1009 that I want to get running but it does not have any batteries in it. Can I take another M1009 and connect the NATO slave cable and get it to start? I don't want to invest in batteries if it want start and I was trying not to have to take my batteries out of the running CUCV.

Thanks,
TT

no

As said. No. (but you can) Take the "jump leads" to the Original terminals, making sure positive does not contact a ground or body metal. DO NOT disconnect whilst running.

Why not just pull your batts and install in CUCV B?

I'm somewhat familiar with these trucks. No way I would do it even though in theory, you could. It's just not worth it.

With no front battery, there is no 12v point supplied.

Bingo. You are correct. Even dead batteries in place will work.

Either do it right or not at all.

Rushing and shortcuts usually end up costing

Yep. And time. Been there, done that.

CUCV's have enough electrical problems when they're equip with two batteries.

Two good batteries. Got to start somewhere

Automotive alternators depend on the battery in order to regulate voltage. If you disconnect a running alternator from its battery, you let the blue smoke out of the alternator. Or worse.

I can imagine ways you could get this to work, but they're all really bad ideas that would make catastrophic and expensive failures all too easy. I would either move the batteries you have, or buy new batteries.

I only have 5 in mine

Slave starting the CUCV


If the rear battery is completely shorted:
No voltage will be dropped resulting in the front battery and the entire 12v truck circuit seeing 24v. Not a good thing


If the rear battery is open:
All voltage will be dropped and the front battery and 12v load will see nothing.


Anything in between these two extremes is possible. This is why the TM -10 clearly states:


"If one battery is missing, DO NOT attempt to slave start."


"Wait 3 to 5 minutes after hooking up slave cable to "dead" truck, before attempting to start it. Damage to the truck’s electrical system may result if the truck is started sooner."


This wait time is an attempt to allow the batteries to receive charging current form the source/slave and become somewhat balanced allowing the 12v circuit to see a voltage close to the designed 12 volts.


Be very careful when slave starting the dual voltage CUCV -- follow the TM.
