Would need regular polarity and reverse polarity diodes ( stud anode and stud cathode). 2 each for single phase (4), and 3 each for 3-phase (6), and would have to isolate the plates the studs are mounted too. That is why I was thinking salvaged from an electric forklift charger, there will be mounting plates (heat sinks) and insulator bushings already in there all made up already With those ebay diodes haw are you going to end up like this. You need 3 diodes going one way and 3 going the other. BTW the higher amperage the diode, the less cooling you will need. I mean we could get all technical and find out the resistance of each diode, and do the I2R calculation's, and then convert the Wattage to BTUs, calculate the airflow under the hood,,,,,,,,,,,,,,, Or just oversize them a bit Quote Link to comment https://www.bigmacktrucks.com/topic/74986-question-on-rpm-limiter-carb/page/3/#findComment-569477 Share on other sites More sharing options...

Geoff Weeks Posted February 15 Share Posted February 15 https://www.aspwholesale.com/rectifier-dr5180pf-delco-cs144-series-hi-output-200a-conversion-alternators even higher output unit, handle 100 amp with ease.

Joseph Cummings Posted Monday at 04:03 AM Share Posted Monday at 04:03 AM You know I was just thinking, being that it is a 3 phase source, the current on each phase should be ( the dc current output divided by the square root of three) So each individual diode is not really carrying the full DC current Quote Link to comment https://www.bigmacktrucks.com/topic/74986-question-on-rpm-limiter-carb/page/3/#findComment-569529 Share on other sites More sharing options...
