I bought some time ago a pos. 6v alternator for our firetruck and a du plug and are finally at the stage where we are installing it. My question is this, do I need to reverse the diode in the plug for it to work correctly? The alt. was bought at Carters and I have yet to recieve an answer from them. Please help.
