The 50 amp one I believe was for the slow GPs and the 80 for the fast. If you are going to a setup like Vince's with individual fuses you could use 20 amps per GP for the fast ones or 15amp for the slow...if you are going to order one of the ones listed on the search link you provided buy like 6 of the one you need as they always break. At least they did for me.
If you need to run the car you can make a jumper wire out of some wire 10 gauge would works. I always carried a screw driver and a wire like that just in case. As long as you pull it off after the car is running it can't cook you GPs. I never took mine off when I used it though I just ran it until I got another fuse.
thanks for the info. much appreciated. where exactly is holmes county by the way?
Man I put the whole Holmes county because I knew no one would know about Millersburg which is where I reside. Holmes county is located about 1.5 hours north of Columbus and south of Cleveland. Coshocton county is just south of me and Wayne county on the Northern side. I guess if you need you could googe or yahoo Millersburg at this point. NOT MUCH HERE.
ok, ive got an idea where thats at, i went riding down by Coshocton this summer, awesome roads, lol, im sure the amish just love hearing all the sport bikes racing thru there at 100+ mph, haha good time though
