I picked up my new-used Griso yesterday and it has a no right turn signal error on the dash. Someone has replaced the rear signals with what looks like the cheapest units they could buy at the Dollar General. I have switched the bulbs around but nothing. I'm planning on changing the signal lights, but is there something else I should check? The left works fine, but when I hit the right I think I hear a faint click from the back of the bike the first time then nothing.
 
Get Carl's schematic for the bike from the tech tab above. Check to make sure the lights have a good ground. After that if no lights, start checking the power side of the circuit. Turn signals are controlled by the dash unit. Let's hope the problem isn't there.

If your turn signals worth a dollar, very likely the workmanship of the wiring too.

My mate showed me his 1100 Griso rear turn signals wiring underneath the rear fender lately, the wires are cut, twisted/joined with a loop or two of electrical tape over the joints.

I replaced mine recently, the proper way to do it is removing the entire rear fender. If you are using the stock turn signals, the entire job can be done in less than 30 minutes.

Well i am confused now. I replaced the rear turn signals today hoping that would fix the problem. When I unhooked the left rear and used my tester, the left front was still flashing but faster than with both hooked up. When I touched the positive terminal with my test light the flashing slowed to a normal rate. When I turn the right signal on, nothing happens. No lights, no indicator, no test light on terminal,nothing. On top of that it has an oil leak at the right cylinder head, just a gasket I hope. Two bolts under thespark plug guard were loose. And to beat all, the oil didn't even register on the dip stick. I had to add over a half a quart to even get it on the dip stick. Not sure if the pressure sensor is working as it didn't come on. The waening light comes on during the ignition sequence, but not at start up like my LeMans does. I love the way it rides, but it is not giving me a warm and fuzzy feeling right now.
 
OK. I know that there is nothing coming out of the instrument panel for the right side. I traced the harness out of the turn signal switch to the first connection, under the left front of the gas tank. I tried to use my test light to find the wires for the switch by turning on the left signal light and finding a wire with current then turning off the signal to see if my tester went out. It never did. So how does the switch tell the instrument panel to turn on the lights?

Absolutely normal. Flash rates are dependent on load. It is sounding like the problem may be the signal switch, or the dash. My suggestion is to take it over to Rider's Hill and have Steve look at the problem. They are probably the closest good tech service shop.
 
I may have to, but they are 200 mile away so I would really like to take care of it myself if I can. The way I reason it is that if it is a short it would have to be in the switch, the dash, or wires before the dash otherwise I would have either a front or rear signal light. Does this sound correct?

Your calling it a short tells me you need to take it to someone. The problem is probably and open. Something isn't making the needed connection.
 
Well, 1st problem down. Signal problem turned out to be the 9 pin connector the connects the turn signal switch to the harness under the left front of the tank. Now I just have to find a way to fix it without butchering the harness. It's just not making a solid connection. Now I hope that the valve cover gasket fixes the oil leak and I'll be in business.
 
See if you can compress the female connector that carries the turn signal current to make a tighter connection with the male plug. A jewelers screwdriver may do the trick. Just be very careful if the female connector is on the harness side. If on the switch side and it ends up damaged you can always get another switch. Replacing a harness is not fun and it is expensive.
