What kind of ignition system does a Yamaha Virago have?
TCI is closed assembly (black box) and one cannot tune it. In Yamaha Virago motorcycles the ignition system components are produced by MITSUBISHI corporation. Mitsubishi produced TCI, rotor (magnet) with exciter (s), and pick-up coils (sensors). Every Virago production generation has its own combination of these components and one cannot mix them.
Where is the TCI located on a XV500 Virago?
On xv500 Virago model TCI is located under the seat (as shown on image above) and on xv535 Virago model it is under right side cover (as shown on image bellow). (Mitsubishi code ??????) Internal parts of J4T033 (xv535 TCI new generation).
Where is the pick up coil on a virago?
The pick-up coil is a sensor (two pick-up coils exist in older version of ignition system) residing under the left engine cover close to rotor ( magnet/flywheel) which tracks rotation of rotor (it is in sync with crankshaft i.e. piston position in cylinders).
How does the Virago ignition system work on a motorcycle?
Before discussing the Virago Ignition Systems it is important to understand how the power to run it gets there. The power starts at the battery and then travels through the main fuse, the ignition switch, the ignition fuse in the fuse box, the engine stop switch, and on to the TCI, and coils.
What causes a virago engine to run bad?
The power input to the TCI may then be intermittent, or low in voltage due to excessive resistance in the switch. In such cases your engine will run badly with various symptoms coming and going. It is hard to riders to figure out what is going wrong because you wouldn’t suspect the sidestand switch unless you knew about it.
What happens when the neutral switch goes off on a virago?
But the moment you shift into gear the neutral switch goes off and that ground goes away. The sidestand switch must now take over. If the sidestand is down (switch off), there will be no ground at all and the TCI shuts down the engine. If the sidestand is up (the ground connection is made) then the TCI is happy and you drive off.
How does the primary winding work on a virago?
The PRIMARY WINDING is made up of a few turns of big wire and has low resistance. This allows 12 volt current to flow through it easily, pushed by pressure from the battery. This current returns to ground (negative battery terminal) through the TCI.
