Why does my Yamaha Vmax have no voltage?
When this happens the circuit opens and you will have no voltage at the terminals. If you do not have a voltmeter, hook up a charger, if you have no current flow, amps on the charger, the battery is more than likely the culprit. You may have jiggled the battery and caused a momentary connection.
What do you need to fix a Yamaha Vmax?
THE FIX: We replaced the stock 1985 regulator/rectifier with a regulator with a regulator/rectifier from a 1997 model. The bike fires up instantly – and – runs like it should because the correct amount of voltage is passing through the system when the motorcycle is running.
Where is the rectifier on a Yamaha Vmax?
Finally we looked at the regulator/rectifier under the left rear passenger peg. On earlier model V-Max’s, the regulator/rectifier is much different than the later model. The new model is much more heat tolerant and has a ground that connects directly to the negative battery post.
What happens if you have a bad voltage regulator?
Too high of a voltage can actually cause damage to various electrical components. Most commonly, the bulbs in your headlights or taillights will prematurely burn out. If you have a bad regulator, it may cause many components such as the fuel pump, ignition system, or other parts which require a minimum amount of voltage to not function correctly.

What happens when a bike regulator gets hot?
The regulator should be warm but not get so hot it melts the wiring. If you see any seepage from the regulator it may have gotten so hot that it melted the sealant inside of the case. When they get that hot they are not long for the world.
