I recently acquired an 82 Honda Magna. The only thing wrong with it was that the turn signals didn't work. After doing basic troubleshooting I determined the flasher was bad. After and a special order, the flasher arrived. While it was a boxy plastic unit and the original was round with a metal casing, the connector matched. I plugged it in and the right signal flashed....switching to the left, the headlight, instrument panel and rear light flashed...with nothing from the left signals themselves...well, the front left light turned off. Could this be from the flasher or am I gonna have to dig into the wiring? Thanks
