CB750. Got an early set of gauges I picked up a few years ago along with some spare parts. Looks like they had been restored or had an attempted restoration. New faces, plastic housings, & lenses. New chrome backs, wires are original but have new connectors & sleeving. They look new, but don't work. Tach needle is at zero until you start the bike. Then, the needle jumps almost all the way around and is jumpy. Goes back to zero when shut off. On the speedometer, I get nothing. No needle movement, no trip or mileage counter. The knob to reset it works. All lights on both sets of gauges work.
Taking apart the gauges (not entirely) revealed nothing that jumps out at me. To go any further, I think I'd have to break things apart - break is a bad choice, but things are pinned or pressed together?
Anybody here in the states want to get these working or have some they would like to trade ?
