    No resolution. The fuses appears to be fine. I tried to hook the battery to the charger to see if i could use the electric starter that way: nothing. I charged the battery overnight: nothing. My knowledge is too limited, I want to learn this bike but I will have to start from simpler more "straight to the point" tasks. I think I'll have to bring the bike to a mechanic. Thank you all for the help.

    Do you really live downtown? I live near the U of M. We have a good group of Airheads here in MN. We have a Tech Day coming up in May and could work on your bike then. You work, we teach. Usually we all learn. Mechanics cost $$
    I try to do it myself. Let me know if you are interested and I can give you details.

    d mpls: if ever an angel tapped you on the shoulder, Airhead Steve is that Angel. The issues which you are dealing with are standard fare for the new airhead owner. Every (generally neglected for a while) 40 year old bike needs to be sorted out. That is a process, not an overnight thing. Take Steve up on his offer. You'll learn more in four hours than you would in four weeks. When you get together with some friendly Mpls airheads, they'll help you learn about your new bike, and show you how to sort it. BTW, have Steve or another airhead show you how to clean up the contacts on the starter relay.

    Keep us posted. I'm in Hastings and it'd sure be nice to learn a few things about these bikes. I've been so frustrated at times... Still thinking about selling my R90/6.
    I'm betting on the battery

    Sanders is your R90 running? If so you could ride it over to tech day as well. You can join us for the day either way. If any MN Airhead riders are interested in the Tech Day shoot me a message and I will give you the details.
    re: starter relay- one of the things I was thinking of, clean the contacts and make sure it is working. If it still is starting with the kick starter d_mpls can ride it to tech day. There is even a chance we could look at it before then. I just stumbled across this thread, strange.

    In MN We have Fleet Farm stores. The Road Runner Batteries they sell are made by Deka which is a Pennsylvania company. I currently have a AGM Road Runner battery in my R60/6 and have been happy with it. They go on sale about once a month right around the walmart (79) price. The Walmart battery might be the same battery, who knows.

    Yes its running. I think I've got it sorted, but would like to learn more, a lot more...Needs a different exhaust. 2 into 1 POS sounds like crap, but I'm loathe to sink even more money into it...
    I can do the valves and stuff on my 07 R1200 but dont have a clue about the old airhead.
    I could write a Tolstoy like novel on this but I have to run.
    Have to see if I can get someone to cover me at work or I'll miss yet another tech day

    The bike is running now. He took it to a local independent mechanic. The mechanic cleaned up some connections and sorted out some of the wiring. I think he adjusted the valves, carbs and timing. It is a toaster tank. D_MPLS is bringing it to tech day so we can check it over some more. Went to his house and showed him some basic stuff and explained how some of the systems work. The battery was 12.76 at rest. Started right up. Rev'd it up a little and I forget exactly but it was nearly 14 volts. so the battery and charging system seem o.k to me.
