My buyer reversed the polarity while jumping and blew the fusible link inside the engine compartment fuse box. I've replace that fuse several times on other cars, and it's a PITA. Hoping to find a vid that shows how to do it, but didn't see any with a quick Google. As usual, you can find Gen2 vids on this, but not Gen1, and it's a different set-up.
