You can cut them and see if that works but you might have to connect them together if it is a closed loop circuit. just use a meter to check the voltage with the stand up and down. if one wire is hot with it up or down you will need to connect the two to trick the bike into thinking the stand is up. But they are both hot then cut the wires and terminate them so they don,t touch anything and you should be good.

Check the ignition timing on my 1995 Virago xv 535 sg bike


Running rich is a carb issue, not a timing issue, and the Virago has non adjustable pickups, the TCI controls the timing advances as you throttle up

I have a first generation 83 yamaha venture 1200 v 4 i have power to only 3 of the ignition coils the fourth coil has tested good by taking #3 lead and plugging into #4 coil. any ideas on what part to...


Okay...when you say power to the coil...I think you mean getting a spark on the plug wire?

All 4 coils should have battery voltage on the red/white wire to each coil. The second wire returns to the igniter (TCI....ignition black box) and it switches that wire off and on to ground to cause the coils to fire. If all 4 test good...then
Check out the TCI, the large box mounted on the coil rack that the connectors are clean.
Now remove the 6 wire connector from the TCI...and test the resistance of the pickup coils which are located under the left crankcase cover beside the stator coil.
you will be testing the following wire pairs on the 6 wire connector
Orange-Black
White/Red-Black
Gray-Black
White/Green-Black
You should see at ambient engine temp...about 110 ohms resistance on all 4 pairs.....if one pair is showing no resistance...you need to test at the lower 5 wire connector just below the seat left side with the same 5 colors....unhook and test....if still having one bad test...pickup coils may be bad.

Stalls, loss of one or more cylinders. Now in shop first $700 to clean carburators and now second $700 to replace an electrical part because of the stalling. Is this crazy?


okay...these are general to Yamaha igniter systems...
so bike is in neutral...shows neutral, kill switch on...
Test each plug cap with a new spark plug...if one or more getting no spark....
Unhook the pickup coil harness and test the resistance (the P U coils located in left front crankcase cover with stator. If resistance tests out fine, ensure the connector is clean and connect.
Now test that both ignition coil packs primary and secondary resistances are within spec.
Verify the ignition coil packs are getting battery voltage to the primary terminal (often a red/white wire).
Ensure the igniter (the ignition black box) also called TCI is getting battery voltage on its supply.
Ensure all connectors clean to TCI.
The only other issue may be the interlocks are trying to shut down ignition....typically a black/white wire from the igniter goes to sidestand relay, tip over switch....both shut down ignition by grounding the control side of the TCI...could be they are partially grounding allowing minimal ignition.

It not geting any spark new coils also


I would test the plug wires and plugs first to make sure the fire from the coils is actually reaching the plugs. Then check the ignition switch to make sure your getting a complete circuit. IF this si not the problem, have your stator checked. It is the piece that goes around the crankshaft, and produces electricity for the bikes systems. If you need additional insight, provide additional information, and I will try to help you further. Thank you for calling on FixYa.com.

Theres no spark


Hi and welcome to FixYa,

A couple of initial checks using a voltmeter:
  • IGN + 12VDC on the red/white wires going to the ignition coils and the TCI;
  • pulsating voltage on the orange and gray wires coming from the TCI going to the ignition coils when starting;
  • ensure that the black wire is tied to the ground;
  • low pulsating voltage between orange & black and the gray & black coming from the pick-up cil connector going to the TCI when starting.

Postback results of tests.

Good luck and thank you for asking FixYa. Happy Holidays.
