Hi Greg,
Before you do this, check under the dash. Sometime it is pretty obvious
as to what is shorting. I just went through this on the BUG-I. It
ended up being the dash light on/off switch had come apart and was
laying on the dash live. Most of the electrical problems I have found
are in the end device, ie. lail lamp, Lic. plt, switch. Otherwise it
best to proceed with a ohm meter connected between ground. Note the
reading, move/rattle wire harness, wires, switches to see if it changes
ang start there.
Good luck, they are easier to fix then find.
