I sold my Dayton a couple days ago and was getting it ready to deliver to the buyer. I noticed the starter running kind of slow and did a voltage check... Battery is only 11.6 volts
The PO had just used a toggle switch for ignition and a large pushbutton switch for the starter. When I pulled them off, I found that he hadn't hooked up the charging system to the battery.
The engine runs without the battery hooked up, so it must have just used the battery for starting.
This engine has a dual circuit alternator-- 3amps DC for charging the battery, and 7 amps AC for the lights. When I checked the voltage, the reading fluctuated all over the place, with the highest reading about 12 v at full throttle.
The alternator must be working somewhat as the engine runs with the battery disconnected, so is this maybe just a bad diode??
Any help would be appreciated, I'm supposed to deliver the machine tomorrow and I don't want to lose the sale.
