I have some bad corrosion on my + battery connector, so I went out and bought those heavy duty connectors from my local audio store. My question is the corrosion is soo bad that the nut to loosen the old connector wont budge and to make it even more difficult it is almost stripped, how can I get the connector off? Only thing I can think of is to go buy a saw and cut the fooker off, any suggestions? Also, please do not state the obvious such as WD40 or cleaning w/a carbonated drink, already tried those. Thanks in advance for your help.
