my son's 108 does not charge. have done some diagnosis of it. starter/generator (S/G) starts the unit fine. ammeter when running is on the discharge side of 0, but the top wire on the regulator is gone. verified wiring, all the wiring is correctly placed on the ammeter, starter solenoid & F terminal on the S/G. so took regulator off. 3 terminals on the side and 1 on bottom. terminals on the regulator are F, BAT, L & i believe the bottom one is ground. the wire from the F on the S/G was on the bottom which i believe is the ground. the wire for BAT that goes to the ammeter was on the F on the regulator and the wire for the cranking side of the solenoid was on the BAT on the regulator and the "L" on the regulator had no wire hooked up. all this unless the 1_8/9 service manual i have has on error on the wire diagram. i knew there has to be 3 wires hooked to the side of regulator. i removed it and believe the connection under the regulator is for ground and believe there was something wrong with the Field wire connected to it. i took the cover off the regulator and the one breaker point set is fried, so i know we need a regulator. what is cannot confirm after reading the Delco Remy IMG-150 service bulletin is how to simple test the generator if it will generate electricity or just be a starter motor. AKA, do we need just a regulator or do we need a regulator and S/G? when i put the test light on the "F" terminal of the S/G, the light would not light. the "A" would light when cranking which would be correct. the "F" would light only when cranking, went out when released the key switch.
