SRS, k56, misc. electrical
Okay I jumpered my battery cut-of relay (K56) and the charging system works normally again. I'm beginning to think that the relay failure was caused by water leaking into the cabin as was the case with other people on this thread.
The drains clogged in the cowling below the windshield and water was sloshing around and overflowing on to the passenger floorboard. It was soaked for a long time before the relay blew out. Now my SRS light is on, the right channel of the stereo failed, and the new K56 I installed blew out immediately.
There are apparently a ton of electrical systems housed or passing under the dash and floorboards on the passenger side. Many have stated that their electrical probs disappeared after the car dried out thoroughly. The SRS light may need to have the codes cleared in order to not light up any more.
I am just going to run it with the relay jumped until it's completely dry inside and then maybe put a new relay in. The risk is thatif I crash, a fire is more likely but that's te only down side I can see. The only circuit that will be hot that would not be if the relay was funtional is the wire from the G(enerator) post to the alternator output which would ordinarily get turned off when the key was off or if there was a crash with airbag deployment.
Is there anything else besides the alternator attached to that circuit below the relay that might draw power with the key off or create a hazard? Seems unlikely...
