I had my 99 DII transported for me, and the battery was dead when they went to load it. They boosted it, but reversed the polarity. I put a new battery in, but it won't start. It has the S and M trans lights flashing, and will not crank. I checked the fuses and all are ok.

Does anyone have any ideas?

The damn shuttle drivers at work do this all the time. 99 times out of 100, what happens is the main fuse for the whole electrical system (80 amp, sometimes more) blows. Not sure where it is on our discos, but on most new cars it's right there at the positive terminal. I don't have RAVE in front of me, but I'll take a look when I get home and see if I can figure out where it's at.

Are you checking the fuses visually or actually check power in and power out?

Might get lucky and have it be a fuse or a tripped inertia switch. Reset the switch and check all circuits with a voltmeter.

But having seen this same scenario a couple times before - you're probably looking at a new ECU - they usually can't handle the reversed polarity.

If you're lucky, they blew the 100A megafuse in the underhood fusebox.

If you're not, they fried any number of the on board computers. The ECU, BCM, SLABS, pick your poison. :(
