Well look anything is possible but I have had a lot of cruisers and had some electrical issues. But when it's water (like a leaking windscreen) you get other indications. I've had alarms going off at midnight. Headlights coming on when the vehicle was parked you know? This 80 is simply brilliant. It goes like a tornado, starts on the touch (well you take my point) all the dash lights work, headlights are excellent, charge is good, even the light in the ashtray works. There are no gremlins at all. Now, the one thing that does make me wonder is the additional wiring that was put in for a big stereo. Seems a member of UB40 owned it once and there was lots of silly big speakers in there and an amp. I have pulled nearly all of that out but there may just be something somewhere I suppose. There was a big fuse block for this and I just pulled all the fuses out.
I'll keep going till I find it but in the meantime I am leaving the truck on charge all the time so as not to damage the batteries by flattening them.
