Re: My Volvo AQ151B Points are Burning Up!
Thanks for the reponses. <br /><br />Follow up prior information/history. I do have a the Volvo manual and wire diagram and I'll reference it to see if there's any way to test the resistor, etc. <br /><br />Well, there's alot of recent history for this problem, which deals with another issue. My cousin took the boat out sking and noticed the top speed was reduced more than normal (25mph vs. normally 35mph wide open), then engine dieseled/chugged a little when shut off (which usually indicates timing issues), then the other issue happened, which is the stern drive (290) popped out of gear at higher rpms-i.e., propeller stopped turning, and the rpms reved up (because no longer in gear).<br /><br />Then I took it out to see what was happening, it idled great, but when I put it into gear and accelerated the engine ran pretty bad and would try to quit. Motoring and slow speeds it ran ok, but as soon as I increased the speed/rpms it ran bad and then the stern drive popped out of gear, causing the rpms to rev up. What could cause the stern drive to pop out of gear? Improper shift linkage?<br /><br />Anyways, as far as the engine and points. We had replaced the throttle cable and may have wiggled some wires in doing so. We zip tied the wires differently than they had been. We then started the engine to adjust the throttle cable, it ran for a few minutes and then quit. That's when we checked for spark (none) and noticed the point pads looked burned out. We replaced the points with an old one and the wire between the points and the condenser smoked and melted after turning over the engine for <1minute.<br /><br />We've had an instance or two when the engine wouldn't start at all and we wiggled the wires near the engine and then it would turn over and start. But this only happened once or twice, but would indicate a faulty wire/short.
