Ok; I need some insight from the wise TR gentlemen about my charging system on TS42756L. I have a newly re-built CR39 generator installed and working well (I think), a new Voltage Regulator from Moss (cleaned and adjusted) a new battery. I am about to store for the winter and have set up my battery tender which brought the battery right up to about 13.6 volts (hand held digital voltmeter). Took the TR for a run this afternoon and on start up ammeter was deflecting well to the positive and the dash monunted voltmeter (aftermarket unit) was showing about 13.8 volts. All OK.
Drove for about 20 miles at 60 MPH with headlights on for a period and then with them off. As I drove, ammeter move to zero deflection and voltmeter indicated 12 volts. After about 5 more miles at speed, ammeter was in the negative, and dash mounted voltmeter was less than 12 volts. Carried on for a while like this and then pulled up in front of the house and idled at about 1200 RPM at which time the ammeter moved back into the positive and voltmeter showed about 12.4 volts. After shutdown my digital had held voltmeter showed battery at 12.7 volts.
Why would my ammeter have been in the negative and voltmeter at less than 12 volts when I was at 3000 RPM and 60 MPH? No lights on at the time.
Confused or not aware how it should be? Thanks fellows.
