What have I fried

pshadwick · December 21, 2006

I tried to install an old inverter on my 01 Silverado. Seems the inverter was faulty.

I have fried something...I can smell it.

The message center shows "SECURITY", and then a red battery. The ABS light is on and so is the fasten seatbelt light.

Everything seems to work OK.

So what multi million dollar piece of equipment have i fried?

Thanks...Paul

Just a plain A/C D/C power inverter? How is it wired? Is it fused? What is wrong with the truck, will it not start? I fyou had the doors open and the ignition in the "ON" position the battery could have been ran down. As for the burnt smell. I would look strictly at the wiring to the inverter, as well as things around that wiring. If you undersized the wire for it it may have been too much for a small gauge wire.

I tried to wire it so that it was only on when the ignition was on. I think the inverter was faulty, but it is not the inverter that is fried, perhaps the BCM or some part of the cluster.

The truck runs fine and evertything seems to work. Apart from the things I mentioned above the gear selector indicator doesnt show. You still see the PNRD etc, but no indication of what gear you are in.

I'll disconnect the battery tonight and see if that resets anything, but the burnt smell suggests something more serious is wrong.

this is why you always put a fuse in your jumper wires

So what exactly did you wire it to and where? The BCM controls all that you describe but I don't see why a relation between the Gear slection indicator and the other indicator lights being lit other than the BCM. Are those lights on when driving, minus the gear indicator?

I did have a fuse in there (20amp) but it didnt blow the fuse. I wired it to a switched wire along the steering column.

The Message center shows "Security" and a red battery, The ABS light is always on as is the Air bag deployed light.

The gear selector indicator doesnt show nor does the "cruise" light light up.

But everyting seems to work.

Note however this is a base level truck, no power windows, mirrors etc (so perhaps the BCM doesnt have that much to control).
