Starter Relays come out of their housing and try to start the bike

Post by cptnapalm » Sat Nov 14, 2020 8:13 pm

2011 Patrol had been sitting for a long while. I put in a new battery and hooked it up. I noticed one of the relays had come out of its black housing. Being careful not to touch the metal, I began sliding it into its housing. WIth no key and the big red switch turned to off, it tried to start the bike. Assuming the bike isn't haunted, this would be a bad thing. (If it is haunted, I know who to call.)

I detached the battery and put the little red cover on the positive terminal so this would not happen again.

Anything to do other than buy new ones?

Did you check your key switch that nothing is jumping or mis-connected. The relay by itself should not be able to start the bike unless the switch is closed somewhere along the line.
Do you know why that particular relay was "out" or not engaged? Just asking in case this was something you didn't do but maybe a previous owner?

BMW starter relays on K-bikes and airheads can cause the same symptoms( as well as most any vehicle circuit). Once started you cannot shut off the bike unless you remove the starter relay from the wiring harness. Reason being is the contacts inside the starter relay have most likely welded themselves together and will not open apart thus you have a continuous circuit which can only be opened(or stopped) by pulling the relay from the wiring harness. Quite common but scary if it has never happened to you.

It happens most after trying to start the bike and you keep hitting the starter button frequently and for long periods of time. This is what causes the contacts to heat up and weld together.

4, or 5 contact relay ( I don't know which you have there ) are cheap; $5-7 at Autozone, O'Reilly's, NAPA, etc. They are all 'universal' in their internals.

Cheap is good! I like cheap. Definitely will get replacements then. No point in fiddling with something like that if $10 will get that done.

The relays had come out, partially, when I moved the seat. I put them back in (no battery attached), but they continued sliding out. With the battery attached, but no key in the ignition and the starter button off, I carefully moved a relay to rehouse it, and it tried to start the bike. It was... weird.

Thank you all! Now onto seeing if letting the bike sit for so long has done even more evil things to it.

Be sure to enquire about the price if they have to get one from the back....

I bought 2 relays at the local NAPA and they were about $25 each!

I presume you mean the insides had come out of the housing. You only got to push the moving contact down and yes it will power up the starter motor. :D

Did you check for mice chewing on wires?
In order for the relays to even get power the ignition and kill switch have to be on.

That would be bad... We actually did have a mouse recently, for a few weeks.

Where to start the examination to determine if that was the case?

Ahh, the actual insides came out/loose of the housing. Understand now. Wonder how that happened?
