Westerbeke w27 Tachometer/Gauge Issues
I just rebuilt my Westerbeke w27, runs great but in our hurry to get it out of the boat we didn't take good notes about the wiring harness and I'm having a hard time getting the control panel working.

Oil pressure gauge works, temp gauge I can get to max out by putting sensor/sending wire to ground but get no movement when it's on sending unit on thermostat

the tach from what I can tell works off of the alternator, it's one of those Mitsubishi 50amp alternators, on the back of the alternator there are plugs labeled R, L and P -- none of which are the DC out -- I need to find the AC out since that what the tach uses.........

does anyone else have a w27 with the admiral control panel? I've tried looking through the manuals, but can't seem to get this figured out......

The R terminal is an auxiliary terminal it should have 7v output. that is the terminal your tach gets hooked up to. The R terminal is also used to flash (or energize) the alternator field if the magnetism in the rotor has weakened from not being used in a long period of time. The L terminal should be for the volt meter or indicator light. Not really sure what the P terminal is for though.

You can also call or take it to your local alternator starter re builder they should be able to identify the terminals with ease.
