Sorting gremlins in the electrics

Suddenly on our return trip home from Saskatchewan a loud noise disturbed start-up for perhaps 5 seconds. Then signal and flasher lights went on the fritz.

Advised that the indicator problem could be related to the Flasher Unit we set out to find it behind the dashboard on the left side. Looking up next to the clutch pedal a silver box was found with a relay dangling. To blink a few lights, this relay was a most complex set of gear.

Fortunately we have two wizards in town who gladly took up the challenge to problem-solve. They were able to repair a broken trace on the Multipurpose Flasher Relay circuit board.

Their thorough examination revealed a pinched wire to the left tail light. It was also observed that the License Plate light (right side) was completely rusted out. Both of these issues were remedied. Then it was determined that a worn alternator belt was causing the noise. Consequently all belts were replaced. Confident that Tulák was roadworthy we set out on a trip westward.

On the Mission Pass descent the RPM gauge died and dashboard warnings lit up. Confident brakes were okay we carried on; however, in Pemberton Tulák simply wouldn’t start. Equipped with “house” batteries and booster cables we were able to jump-start the mog and return safely home.

The team was reassembled. A multimeter suggested the truck alternator wasn’t charging. Following the advice a comrade on the Mercedes Benz Unimog forum provided, we once again have a working charging system. For all the details check out our post on benzworld .
