Well, I got around to the fuel tank finish up task and I also checked charge voltage at battery. Alternator is doing it's thing at about 14.5volts at battery at full throttle and about 13.6 volts at idle. At rest battery voltage was 12.7v.
The battery may have been at bit low because earlier today I ran it out of gas and forgot to go out and turn the switch off for about an hour, then I spun it for about 20 seconds to be sure that it actually ran out of gas instead of for some other reason. It was out of gas at the primary pickup.
Put in the reserve pickup and pressed on the tank in reserve position to help fuel into the filter and it fired right up. Then I checked voltages.
The light is still on. I guess next is dig back down inside under the battery and check fuses? At least the 2 amp fuse (F2)?
Am I close?
