sidestand relay?

[Grez007]

hello all, I have discovered that my bike will start while in gear with the side stand down. or if i start in neutral and kick it into gear with side stand down and release the clutch it does not die as it should. I did some digging and found that there isn't a side stand relay present on my bike, the harness is there(it's BLUE) but nothing plugged into it. is this likely my problem? I see that bike bandit lists the part so i assume its still available but are there other alternatives? its pretty pricey, and i'd like to be pretty sure thats my problem before dropping the $$. I tested the side stand switch and it works as it should and the icon on the dash comes on/off as it should

I could be wrong, but If the relay wasn't there I wouldnt think you could start the bike at all... I have a TCI box that for some reason would allow me to do all those things, hooked up new box and it no longer allowed me to do that. Unless someone has cut the black and white wire running to your TCI box...

I'll almost betcha if you look at your side stand switch somebody spliced all 3 wires together! The original problem could have been the switch went bad and the bike wouldn't run in gear when letting the clutch out, a very common problem, and the P.O. fixed it their own way...

where would someone splice them together if this was the case? The connector was together and checks out how it should as per the manual. Im certainly no electricity surgeon but i would be inclined to think if they were jumpered someplace i would get continuity across all terminals of the harness? also I checked the wiring diagrams in the tech section of the forum with an electrician friend and the bike would still start and run without the sidestand relay plugged in

The most logical place to have tied the wires together is near the side stand switch. But since you say the the side stand indicator on the dash is working correctly then it is unlikely that someone tied the 3 wires together.

 

Try this, at the connector where the side stand relay is supposed to be, connect a temporary jumper wire from the black wire to the black/white wire. This should prevent the bike from starting and it should kill the bike if it is already running. This will prove out that half of the circuit is or is not working correctly.

 

Try unplugging the side stand switch connector, the bike should not run. if the bike does run with the switch unplugged, then you have an issue with the blue/yellow wire that will have to be tracked down.

Yah! The usual "Fix" is to unplug the connector and put jumpers on the socket and electrical tape, so obviously your issue is elsewhere. When ohm'ing out the switch contacts, you need to see zero ohms or very close to it! Even 4 or 5 ohms will fool the circuitry into thinking the switch is still open! You state the relay itself is absent so I did a little investigating and yes indeed, with the relay missing, ground to the B/W line to kill the ignition in cases of the side stand down in gear without the clutch being depressed, etc can never be seen! Unless there is something else going on with the circuitry putting the relay back in should return things to normal!

PS check with Marcarl, he may even have a spare relay laying around unless he ditched all of his 1st gen stuff. Pretty much all of the relays with the exception of the fuel pump relay should be interchangeable if memory serves me correctly...(which at my age sometimes don't work anymore!)

thanks for the replies fellas, I'll go down to my local recyclers this week and see what I can find, I know he has a 83VR, hopefully the relays are still in it. I wouldn't mind so much just leaving it the way it is but it needs to work correctly to pass a safety certification so I can get my license plate for the bike

i jumpered the black and black/white in the plug where the relay should live, the bike turns over but will not start. Also if i start the bike(no jumper) then insert the jumper it does kill the engine. Also i took out the cooling fan relay and plugged it in where the sidestand relay should be hoping they are the same but im not sure they are because with that relay the bike turns over but wont start(just like the jumper scenario) and fires up as soon as i take it back out, but again im not certain all the relays are the same internally.

EDIT: i checked the bike bandit website and the relays located behind the dash all have different part #s so

based on that i would assume they are not necessarily interchangeable.

OK you have verified half of the circuit is good.

With bike turned on (does not need to be running), at the side stand relay, check from the red/white wire to ground, there should be 12V.

Check from the blue/yellow wire to the red white wire. There should be 12V with the side stand down and 0V with the side stand up.

 

With the bike turned off. check voltage from the blue/yellow wire to ground, it should be zero. If it is zero V then check resistance from the blue/yellow wire to ground, it should be infinity. If it is low resistance then the blue/yellow wire is shorted to ground somewhere.

thank you very much for your direction on this Jeff, the plug checks out as you describe above

so i should be good once i get a new relay ordered and installed. Thanks again. Paul

What state are you in, I thought Missouri was the only state that did safety inspections..... They never even checked that on the bikes I took in. But I do agree those do need to work because it kind of stinks taken off and forgetting your kickstand is still down...

[snyper316]

Wouldnt all the relays be the same up there? I am thinking I swapped mine around at one time trying to see if I got the same results.

im in Ontario,Canada. I even called the place where i want to get it inspected to ask what they check. The guy there specifically recommended that the sidestand kill system is working. I have found that most places aroun here are prtty thorough with safety inspections
