This is a home made stack diode to replace a blown diode. I came up with this because I blew a diode in my ES6500 Honda generator by jumping the dead battery but screwed up and reversed the leads and that stop the generator from producing AC. I did not want to pay the large price for the OEM part. Replaced the blown diode and off and running. I have built 10 extra and sold all of them with no complaints. I just had a request to build some more so here they are. Make sure you look at the pictures for the correct install position. The black pin must be on the flat side of the plug and opposite from the clip where the tie wrap goes through it. Make sure you match up the pictures. I am not responsible for any damage to your systems. Try this at your own risk.
