Sart with basic maintenance. CHeck fuses for corrosion ('cept the 92 I think uses the the plug in type which usually don't have problems with the points of contact, re:previous post). Check that the alternator is charging, what you describe could be a faulty alt., wtih only the battery carrying all the electrical duties. If you don't have a multimeter, get one, a cheap $10.00 one is fine. re: the o.d. that's probably a wire grounding out against the frame or a bad relay or switch. Your o.d. is going in and outwhen you re in Reverse thru 3rd gear ot you would have destroyed the o.d. by now. This is simply a switching problem of some sort. Work out the charging first before you trouble shoot the o.d. but I'ts probably the relay. Good luck, Patrick.
