I have an 83 Aspencade that I've just recently had on the road. I notice that the voltmeter is reading low. Checking with a multimeter, the voltage is higher than shown, but still low. Looking down beside the battery where the three yellow wires come down, one of them has had a section cut out of it. Anybody know why the PO might have done that and, if I reconnect it, will I blow up the electrical system or might I get back my missing voltage?
