November 10, 2010I have an 89 F250 with a 7.5L. My alternator went out due to being the stock alternator and running a plow with it. I have the largest battery that I could fit in the space, but it still burned out. I want to upgrade to 130v, but am being told I need to rewire the connections. Could anyone help with diagrams and an idea of what alternator would be a good match?
Thanks for your help.
