How to keep your electrics in tip-to order
You don’t need to be an expert to give poor electrics a simple service
Regualr maintenance is the best medicine for dependable ’leccy
EVEN THE MOST pristine older bikes can have electrical issues lurking. So it was with editor Jim’s Yamaha DT125R. Every time he applied the brakes on a night ride home, the headlight would fade to the point of uselessness. If he had the temerity to use the indicators at the same time, he was plunged into darkness. Like many road/trail hybrids, the DT’S electrics are at best marginal but they should deliver a little more than the gaffer experienced. With tiny generator coils and a basic four diode rectifier feeding a little battery, everything needs to be in good shape.
Any trail bike used for its intended purpose is going to get dirt in all kinds of awkward places. Wires that have been flowing current for years are prone to degrade too, especially when the
production accountants have pared down the wiring specification to the very lightest.
With spring not yet sprung and Jim determined to use the DT daily, we thought we’d best do some testing and inspection to restore bright light to the little Yamaha.
