Hello all,
I have a 2004 Crownline with a 4.3 mercrusier and thunderbolt V ignition, with 150 hours. Took her out yesterday for the first outing of the year and all was fine until it wasn't. While driving about 30mph, the boat lost all power to ignition and left me dead in the water. I've checked my 90amp fuse at the starter, all good, reset (wasn't tripped but figured why not) and checked my 50amp breaker, all fine, I've checked all my fuses under the dash and we're all good there too. I have power to all of these items as well when checked with a test light, I don't have a volt meter to measure voltage (broken, but will purchase another for testing). When I turn the key, the gauges don't activate, there's no warning alarm and nothing happens. Yet, I have power to my bilge, blower, horn, and even my trim works- radio doesn't work. Anyhow, I jumped my solenoid and my engine turns over and with the key switched to "on", I can hear the gauge cluster turn on. From research online, I've seen some post that there is a 15amp ignition fuse somwhere near the distributor. The trouble is, I can't see any place that there could be another fuse. Perhaps this isn't common among all 4.3's and may depend on the type of ignition system it has. Any help here would be very much appreciated, am I missing any fuses? What else should I check, thanks all for the help.
