Good morning together, what is the A terminal and B terminal at the generator. At Bosch generators you find B+ and D+ and DF and D-. I've read the wiring installation information but I don't understand it right. Wolfgang
On the stock generator, looking from the front, the terminal on the right is the field, the left is batt.
Generator Fun Good morning Wolf ! . The 'A' terminal id the armature or D+ The 'B' terminal is the DF Delco generators are 'A' circuit so to test you bridge the A & B terminals then spin it at idle , never ground the field like on a BOSCH ('B" circuit) Generator !. Do not EVER rev. the engine over 1,200 RPM's when testing as you'll burn it out . DO NOT " flash " or " polarize " the generator ! . this is a last ditch " Hail Mary" thing done only if the generator has reverse polarity or other malady . Connect it all up and start the engine , rev. slowly and observe the voltsge begin to rise to about 7 VDC at the battery . If no charge , STOP and let us know , we'll walk you though simple generator testing .
Voltage F terminal to generator F terminal? Hello, can someone tell me what is generator F terminal. In my wiring instructions is wirtten no. 24 voltage F terminal to generator F terminal. What means F terminal on a Bosch generator? Asks Wolfgang
F Terminal Is for the Field or exciter curcuit . Grounding this forces the generator to produce maximum current so ! DO NOT ! Rev. the engine a bunch whilst testing when it appears to not be charging ! if it suddenly begins to charge , you'll burn out the armature before you can blink .
