The port rev counter in the saloon and on the flybridge suddenly stopped working while underway on my Princess 415. Back on my berth I managed to connect the alternator signal cable from the starboard rev counter to the port rev counter and the port rev counter worked OK which pointed to a wiring fault. On inspection of the port alternator, there are 4 cables attached as follows:
1. Heavy duty Red
2. Heavy duty Black
3. Light duty Yellow
4. Light duty Brown
I disconnected the yellow cable as it was a spade fit and on starting the engine found the battery non charging alarm operating so assumed that the brown cable was the 'W' terminal feeding the rev counters. I assume this brown cable must go into the loom and split at some point to provide separate signals to the lower and upper rev counters. Rather than trying to trace the fault through the wiring loom, would it be possible to rewire the 'W' terminal with cables that go directly to the signal input on the back of the rev counters?
Alternatively is there somebody out there who knows where the 'W' signal might split to the lower and upper helms so I can check the connections involved.
