If I increase the resistance value AIR4 coming from the current coil AICR5, will that let the transistor AIQ1 turn off? Or maybe shunt some off from the coil to ground through a resistor?
It looks like current flow from the coil is keeping the transistor NTE199 NPN base biased and that is keeping the transistor flowing current which is keeping the run relay K4 engaged.
This circuit is very sensitive to detecting an AC load and keeping the 1965 boat generator running.
The problem is I added 2 digital gauges to measure the AC voltage, and that is enough to keep the gen on after it autostarts when it detects a load. It will not autostart with the gauges on in the circuit, but the gauges keep the gen running and it should be off if there is no other loads than these 2 gauges. No point keeping the gen on to see what the gauges read.
I measured the vac coming off coil, with no load and gen on, it reads 0.4vac
With both gauges reads 1.9vac
With a 10 amp load reads 4.1 vac
Higher loads, it reads about the same 4 vac.
