Hey, guys. Local sheriff's office obtained an MRAP. They've been having some problems with electrical gremlins. I've done what I thought was a thorough search, but I cant seem to come up with a "free" source for a TM (20-level?) on that vehicle. Just trying to help these guys out. They have a mechanic that went to the MRAP University... but according to one deputy, the guy wasnt exactly a 4.0gpa performer, either.

Took a look through the manuals here with no luck either. Anyone got some tips for me? I've come up empty handed so far.

Try using the M1083 MTV manuals, that is what the Caiman is based on. The Caimans seem to be riddled with various problems right from the factory.

The Caimans most LEOs are receiving are Caiman hulls that have been pulled and upfitted to the Caiman Plus chassis. I think they weren't real attentive during the upfit. While the chassis is at zero miles, everything in the hull may have been around the world.

i think what NDT has said is holding true. while the basic mechanical systems on the vehicle are solid, it seems like everything else goes wonky. i was mechanic in the '90s. this chassis is a whole new progression and i'm not really familiar with it. what they sounded like was a bad ground in the aux lighting system... when i suggested their mechanic break out a multimeter... they broke out laughing. wish i could at least hook em up with some wiring schematics. as far as they know, the chassis they have never saw deployment.

All levels of the TM's are restricted. I tried and could not find even the -10 to get air pressure and confirm run flats on 3 wheels I have. If you score a 10 or 20 please pm as I would be interested.

I know this is an older post but my local PD has a BAE MRAP that has electrical problems. Has anyone found a solution and or a manual? This one seems to possibly be a charging system problem.

Thanks

if its a charging problem have them look at the Alternator for a Name tag to see what model it has. if it is a Niehoff they have troubleshooting guides for this models on their website

We have a Caiman, i ran it one day and the voltage Guages (both 12v and 24v) started dancing all over the place, then poof, smoke from the invertor on the outside under the hood by the firewall. we have been trying to figure out the issue, but no luck so far. have a guy from our local National Guard armory coming to try and help tomorrow. Ill let yall know what i find out (IF ANYTHING)

Agreed with Suprman, disconnect the inverter, charge the batteries, and verify that no vehicle electrical loads are causing the overload. I have had the inverter burn up on a similar vehicle, not a fun experience. More modern inverters are available.

Our SD here also has a Caiman. Supposedly for SWAT, but mostly seen in parades. (In county of 50,000 people). Guess they couldn't resist the temptation of getting a large MV to replace the aging Bradley they had.

My NAPA guy says they are in there all the time looking for parts.

"Never confuse acquisition with maintenance!".

Good luck finding the problem..

I will look through my manuals and see if there is any schematics that might help you. Our Caiman is in great shape and I have had no electrical issues with charging system. Had an A/C issue which I fixed, and then I solved the sticky brake issue.
