The bildge blower on my 155 isn't working. It stopped sometime last summer I think, and am fixing it before getting it out this year. All other electrical is working fine (lights, bilge pump, stereo, starter all good).
I checked the voltage to the blower and it looked OK, so I assumed the blower itself was dead. I ordered a new one, but decided to re-test the old one before replacing it. Sure enough, when connected directly to a 12V source, it goes just fine. So now, both new and old not working when plugged to the blower connector, but spin fine on a 12V source.
Thinking I must have a loose wire and got lucky with the first voltage reading, I double checked voltage again, and again. Every time it is 12V+ when the blower switch is engaged, and then 0V when switch is open. Not sure how that makes sense when plugged directly to 12V that it spins, but not when connected normally. I double checked the fuse -- it looks good, and when the fuse is pulled there is no voltage at the blower plug or light on the switch.
Am I missing something obvious?
