Testing flasher relay

So, how do I test the flasher relay? 7 pin suzuki.

I overloaded the relay, causing it to burn out. Soon after I corrected the problem and ordered new relays - didn't work. I ordered another one, that didn't work either. (they just light up solid, no flashing)

I have a third one now, this time from USA. Looks exactly the same as the other 2 non oem ones.
I'd like to test my system and the relay to make sure this time.

did you connect al of the wires with all of the lights?
Sometimes it's solid because its missing a load
 
You'll need the proper pinout for that relay before applying power to it. Do you have a service manual for the bike? Does it detail out which pin is which? Or perhaps there's a wiring diagram?
 
I don't have one signal as it snapped off. Would adding a led strip as a mock up work, till I get new signals.

I found one of the older relay's they all seem to have build up on one of the pins.

left is the old relay, right is new.


I have no idea how to read wiring diagrams, but i'll look into it now.

Post the wiring diagram of your flasher. the white stuff is just normal corrosion depending on the moisture. If it still works, just clean it up by sanding or a brass brush.
 
I wired up all for signals. The signals still aren't flashing. I checked the manual and I performed the test on the relay, both passed the continuity test.
I believe the problem lies within the wiring harness.
How do I check that?

If the wires were burnt wouldn't the leds turn not turn on.
 
Do all the signals turn off when you unplug the relay?
What changes have you made to the bike since the last time they worked?

No, the signals stay on without a relay in place.

Just replaced the relays, all the 3 new ones i've tried stay solid. I also rode with out one of my signals for a long time. If it makes a difference the front to signals are yellow led strips.
 
Sounds like there's a short in the wiring. Will the lights turn off when you cancel the turn signal?
 
Power is getting into the turn signal circuit from some other source. They're not flashing because with the power being fed in from elsewhere, it's irrelevant whether the flasher switch is open or closed.

What did you bugger up in the wiring?
 
I should clarify: If the symptoms are being accurately described, the problem is not the flasher relay. It's the wiring.

pull everything back to basics and work your way forward.

This actually sounds like a fun little electric issue to sort out to me.

its not going to get any easier than this to test the relay out.

Relays are simple, Connect them up to complete the circuit (per say) , then use the right pin to trigger the relay. Connect the on/off pin to the + to test to see if the electromagnetic switch and see if it is actually switching on/off.

Possible, but very unusual for power to find it's way into some wiring. Isn't it more likely that there's short to ground? It would require the relay to be on the no-load side of the circuit, based on his symptoms.
 
I suspect that the source of the voltage in question is because the bike in question has had aftermarket modifications done to the turn signal circuit, and whoever did it has buggered something up.

Let me clarify, when the turn signal switch is on, the signals are solid regardless of whether or not the relay is in place. When the signal is cancelled the light is off.

Does that change anything or do I have to rewire the signals to diagnose the problem?
 
OK that's a very different situation, easier to deal with. But still - Do all of the turn signals in the system use the stock bulbs?

No? Make it so. I betcha the relay will work fine.

Turn signal relays rely on being connected to a circuit having the correct resistance in order to flash at the correct frequency (or at all).

My signals are all after market leds. So, I need to have all the same signals otherwise it won't work?
