"This is it. Next time, this
"This is it. Next time, this motor goes on the bottom of the ocean. 1990 SeaDrive (225 Johnnyrude) Tachometer on starboard engine became erratic. Would read double, normal, double, etc. Then I noticed that the charge was wide open. Voltmeter was reading in excess of 16 volts. Confirmed it with DVM. Too cheap to buy a new rectifier/regulator, went with a used one. Everything back to normal. For two days. Now I notice that the tach is bounding around again, reading double, etc. For the moment, the charge is still at 14.5. My question is, is there anything on the motor that can ruin the rectifier-regulator assembly, or is my problem caused by being cheap and using used parts?"
