Turn Switch Relay Problem?

[kjg_1977GS750]

Model: 1977 GS750

Problem: Both turn signals initially work either before bike is started and/or after bike is started. However, after bike is running several minutes turn signals stop operating. Signals sometimes work after turning off bike and restarting. Furthermore, tapping turn switch relay with screw driver [sometimes several times] initiate active turn signals again.

Question: Is this indicative of a bad turn switch relay? ...or are there other issues?

Many thanks in advance.

Everything matters here.
Connections on the bulbs
All the grounds
and the relay.
I'd clean the grounds first and then the bulb and connector.
If it still is a problem replace the relay.

Hi Mr. kjg_1977GS750,

Yes, clean EVERY electrical connection and ground on the entire bike. All of those 30 year old connections need to be freshened up. Battery condition and charging system condition have a lot to do with blinker behavior. Make sure your battery is fully charged and test the charging system. Testing procedures can be found in the links below.

If you're tapping the relay and it temporarily works, it means you turn relay is faulty.

I've been threw this with my 650.

Yes, technically it Could be dirty wiring, but why waste your time?
Just goto Autozone or any parts store and buy a 3 prong turn signal flasher Unit.
They usually cost around $10.

And get yourself a simple wire/connector kit, so you can connect the wires to the new flasher relay.

Do NOT goto the suzuki dealer, they will want $80 for a crappy stock relay!

These relays are notorious for being faulty, on these suzukis.

It's a current driven system so clean the grounds anyway.

Update: After: (1) testing battery; (2) cleaning battery grounds thoroughly [though grounds did not appear dirty/corroded]; and (3) a 70 mile country-road ride, problem did not reproduce itself. So, I'm optimistically reserved.

Note: For readers of this forum at large [and those specific to issue], problem occurred after proper "blinking" of lights when either the engine was "on" or "off". I note the turn lights themselves turned "off" [and remained so] when the problem occurred.

MANY, MANY THANKS! to all who read and replied to my posting.
