Reply to AMEDEE's Post: tech states volt too high
Expert:  Amedee replied 8 years ago.
Oh... ok

It sounds like the charging system voltage is too high.

But to get a complete analysis of the charging system, the battery must be checked first to see if its in good condition.

It all starts with the right battery. If you have the wrong battery in there, than it will need to be replaced with the correct one.

After we know the correct battery is in your vehicle, the next step would be to actually test the battery to make sure its good!

A fully charged battery must have enough cranking capacity to provide the starter motor and ignition system with enough power to start the engine over a broad range of ambient temperatures. Even if its charged, it could still be bad causing a no crank condition! I would rec to get it load tested at a shop or at a battery store. A battery load test will verify the actual cranking capability of the battery. This is the best test. Or u can take a voltmeter and put it on the battery and crank the engine over. (Be sure the battery has a full charge on it.) If the volts drop below 9.6, the battery is bad and needs to be replaced! Just be sure all cable connections are clean and tight. Not only at the battery, but on the starter, engine and frame! Positive side as well as the negative side.
