Helping a friend figure out his Westerbeke 8.0 BTDA issues. Here are the facts:
- 2001 Generator
- Two oil pressure switches. One on top is "auxiliary" and is for System Monitor, one on bottom is primary and is used for low oil pressure shutdown
- Temp gauge and oil gauge, or their senders, don't work
- Remote panel start switch blows 8A fuse when in "on" position. Replaced start switch - no change.
With remote panel plug disconnected from back of control box to remove the remote panel as a variable, the following exists:
- 8A fuse blows when auxillary oil pressure sensor is plugged in when starting from generator toggle switches
- with auxiliary oil pressure sensor unplugged, it starts fine from toggle switches and continues to run while preheat is held on. As soon as preheat is released, generator shuts down (but 8A fuse does not blow).
So, I'm working on a sequence of debug and isolation steps to get to the bottom of this. I first plan to get it working normally with remote panel disconnected by replacing auxillary oil pressure switch and also jumper the three shutdown switches to see if any of those are bad. Is there a tried and true process to isolate a gauge failure or a sender failure?
