Hi, I am soliciting help from this incredibly wise forum. I thought at first this was a random problem, but now it has happened twice, I am not sure.
I have had a 'surge' blow my electronics, AM/FM radio and my navigation lights twice in 2 years. I can't afford to replace my electronics again after I've installed this 3rd replacement. In both cases, my knotmeter / depth gauge blew, my AM/FM radio fried and the incandescent light bulbs in my running lights blew. In all cases, not a single fuse blew. Interestingly, my mast lights were OK, my VHF radio was OK and my cabin lights were OK. The first time all were on, this time the AM/FM radio and instruments were on, but the running lights were off. I am thinking it may be a voltage regulator problem on my alternator, I have an A-4, but can't be sure. Maybe the safest thing is to replace it anyway. (Last time this happened, I had my mechanic check the alternator and he couldn't find anything wrong.) One other solution could be to run my electronics and AM/FM radio (when I replace it) off a separate circuit which is not charged by the engine. That would keep the circuit isolated perhaps. Anyone had this happen to them or have any ideas? BTW - I don't cruise in my boat, just race socharging the battery through shore power is not going to be a problem. -- Ian Matthew "Siento el Viento" C&C 29-1 San Francisco Bay
