    R 65 Electrical Gremlin

    Last fall bike started, then stalled. Starter engaged and gave a couple revolutions then quit.

    Switched off key, tried again, nothing: no lights of any kind and no starter.

    Took apart headlight relay, cleaned contacts, got lights, starter worked, then quit.

    Checked ignition switch connections: OK.

    Took apart run/off and starter switch: cleaned and put back together.

    Replaced head light and starter relays: all lights work, no starter

    Pulled ignition switch: no continuity to hot in OFF , continuity to 2 pegs back to hot in PARK, continuity to all in ON.

    Here's the funny thing: with ignition OFF closing the start switch pulls the starter relay in (but nothing else happens). With ignition in ON, closing starter switch doesn't do anything (all other lights come on, idiot lights go out when the run/stop switch is open).

    I would go to starter solenoid to check for juice with ignition ON, clutch in and starter closed, but I want to figure out why the starter relay reacts to starter switch with ignition OFF.

    It's an '82. Any ideas?


    Thanks,

    Rick,

    Did you remove and clean both + and - connections to the battery, as well as the other ends of both those cables?

    I'm getting 12.73 V everywhere in the system.

    If you have a loose or corroded connection somewhere, it will meter out fine because there is so little current draw for the meter reading, but it may not work when you hit the starter and really draw a lot of amps.

    You may have 12.73 (which isn't a lot) with no load on the system but if you have bad connections or corroded wires at the battery as soon as you introduce a load like starter or lights you current flow goes to zero and your voltage drops to the basement. When you have a loose or corroded connection its kinda like the garden hose with a kink in it, you got water at the end but not a lot and very low pressure until you remove the kink or clean and tighten the connections.

    I jumpered the + and - posts on the solenoid--starter cranked OK.

    The lingering problem was the new starter relay not pulling in with the ignition switch on, but it would with it off.

    Wrong relay. Pin pattern was the same, but internal circuits were different.

    Original problem was starter switch. Very sloppy fit and contacts only made 1 in 4 tries, and then only momentarily. Good used switch and now it works like it should.

    Thanks for the replies,
