I'm not good with electrical probs. The electrics are giving me a hard time, the problem is, at numerous times, the guages and head lights, bounce around giving false readings, and durring these times, the car will not shut off, like its dieseling, when the bouncing guages stop its o.k. I've just installed the mark vii fan, could this be the problem? At night i'll switch the fan off and on, and it makes the lights go out momentarialy. Any ideas, or is this one bound for the electric shop?
