I installed a brand new, not rebuilt, brand new military starter in my M-1009 a couple of weeks ago.  Two nights ago I tried to start it and nothing happened.  All the lights that normally come on for start did, the wait light went out, I turned the key and silence.  I took the key out, opened the hood to check the battery cables and the Bendix started spinning so fast that I couldn't believe it.  Smoke started coming out of the starter area.  I tried to disconnect the battery cables but couldn't.  The spinning stopped, the smoke cleared and I started to look at the damage.  I ended up taking to a shop to work on it.  Dropped the starter and found a black fluid had come out of it and dried.  No visable damage to any wiring on the starter.  Four wires at the firewall on the passenger that are fuseable links had burned badly above the fuseable links.  I cut these down until no wire damage showed, added new wiring with aircraft quality butt splices.  Sent the starter off for repair.  I replaced the starter relay under the dash with a NAPA AR-135 that is said to be the correct replacement for this relay.  The shop replaced the Bendix, bench checked it and returned it to service.  I installed the starter, again all normal lights came on, hit the key after the wait light went out and again nothing.  What is my next move?  I am considering replacing the entire wiring bundle that those four burnt wires were in?  Thanks in advance.  Ed

That starter should be a 24 volt starter, and although a 12 volt starter might take the 24 volts, it would spin fast, but the solenoid wouldn't take it for long.
Are you sure your new one was 24 volt?

Yes, positive, no doubt what so ever.  It is a military issue starter for the CUCV M-1009 & M-1008 diesel 6.2 engine.  It didn't come from some civy shop it came from the military motor pool.  It was designed expressly for the M-1009 & M-1008 vehicles.  When I got it I went the extra step and checked it out, it is a 24 VDC starter.  My problem is one that is VERY common for this series of vehicles.  The starter relay welds itself after enough hours of use & causes this to happen.  I know what the problem is I was looking for a fresh solution to it.

Being as this is my daily driver & I use it every day a 12 VDC starter would not have lasted a day much less over two weeks.  Also it was turning normally each and every time it started.  If it had been a 12 VDC I would have known it the first time I cranked it.

Beg to differ with you on the starter lasting more than a day...it is the solenoid that wouldn't last.
And yes...it would spin fast, kinda goes along with you saying it was spinning so fast you couldn't believe it, but yes, I think one probably would have noticed, but you would be amazed how much is not said when someone asks a question here.
I have been running 1008's, 1009's, and 1010's for about 15 years, and have not run across this common problem.
There are some common problems, but that isn't one of them.

I am mildly curious why you are buying NAPA parts, for a military vehicle, or is this a privately owned vehicle?
