    I have seen a thread regarding this but can't find it anywhere. -

    ABS Pump stays stuck on after it engages. Will stay on even when the bike is turned off. Temporary fix is to takethe tank off and smack the ABS pump until it kicks the relay....until happens again. Battery is fresh.

    I know I've seen a thread discussing which relay is required and the weird cover on the ABS pump that needs removed to access the relay but I cant find it anywhere.

    Experts?

    There is a description of how to remove the plastic cover over the relay here:

    I don't know about a substitute relay. If you can't find one, I'd go looking for a used one. There are plenty of scrapped units around because of hydro issues. They should have good relays.

    Absolutely no on a used relay, they all develop the same problem.

    I wasn't aware this was a very common problem. I have heard of it happening, but it doesn't seem to affect a lot of people. Mine is still happy after many years.

    . I think you're taking about the wrong ABS module, The early ABS modules don't have a common relay problem at all. In fact compared to the problems with the later servo/abs unit the earlier ABS only units are bullet proof.

    Once the contacts start sticking they will keep doing it from what I have seen/experienced. The problem starts with a weak battery.
    Replacement is required.

    The same applies to the Load Relief relay

    My experience has been with this exact model year.

    Yes, but it's not exactly a "common" problem. Think i've had two modules in the workshop with a relay problem in 25 years.
