I wonder if the electrohydraulic controls are still working?
I'll hold your beer while you check.Quote:

I have struck a problem with L.E.D. lights on trucks and trailers as well. I used to just bridge a spike protector across the battery terminals but welding near a L.E.D. light has blown a few so I now also disconnect them at the plug. The newer multivoltage lights don't seem to suffer as bad but why take chances?Quote:

typically the HV will track through the carbon in the tyre rubber and conduct to Earth, heating up the tyres until the y explode, and start burning. With the tyres alight, the rest of the vehicle follows pretty quickly.Quote:
