Hi. I am about to change the Stator to Rectifier plug (the one with the three yellow wires) and want to know how many amps pass throught this connection and the yellow wires. Cheers Toni
Divide the watts supplied by your stator by the voltage. 520 watts divided by 12 = 43.3 Not sure if the three phase is 520 or not . I am not an electrician but this was a rule of thumb guide give to me by an electrician. Steve
Thanks for the replies. Going to cut the old terminals off and go to my local model shop and get the bullet connectors. Will post back when all done. Cheers Toni
Folks this is only true for the single phase systems and is incorrect for the three phase 520W systems on the later 748/996/998 systems . There are a different set of electrical threories that apply, put simply 3 phase has much higher efficiency (why it is used as the standard power transmission system across the western world) and the conductors only need to be approx 75% smaller than the calculated size for a single phase load. In this case the current running through each of the three yellow a/c wires works out at around 4-6A with the reg at 520w output assuming the load is balanced and each of the three connectors is making a perfect connection. My advice is not to use bullets unless you have no option and if so use the largest and best quality ones you can find and get a goood quality crimping tool to make the connections. These connections have to be kept scrupulously clean or sealed to eliminate the high resistance and wire burning that has been mentioned which is due to the imbalances on the three phase load if one of the connectors gets corroded and starts to heat up.
