How do I change the voltage meter on a bailey orion

You changed the battery? Have the battery load tested with a carbon pile. The problem could be a bad cell in the battery IF that is not the case it could be an ECM issue. Alternators are internally regulated

You need to test your alternator for too much voltage. Any digital volt meter that reads DC should work. With the volt meter reading across the battery, run the engine up to about 2000 RPM and check the voltage; it should be about 14.5 volts and never above 15 volts. If the voltage is high, you can cook your battery as well as having your lights burn out quickly.

Check wiring with a test light or volt meter. switch lights to low beam, connect volt meter N probe to a good ground then probe the light socket for the low beam power cable, should show battery voltage, now switch to high beam and test for battery voltage if ok remove the grounded meter probe and probe the cable in the socket that you have not tested this is the ground cable, battery voltage should show if ground cable is ok. If no voltage repair cable ,If voltage present check filament on bulb high beam perhaps the new bulb is faulty.

Brother Mark, changing the battery with a new one being done won't make the light go out, as you noticed. Light is still on so you changed the alternator. Good, but the battery light is STILL on. This only means that the charging circuit from the alternator is not working in the voltage regulator or the wiring is not connected properly to the alternator/regulator. A new battery will show over 13 to 13.5 volts not connected. An old battery will still show 12 volts and still be weak or bad. After connected and engine running, the system will show at least 14 volts because alternator/regulator is working properly, using a voltmeter/load tester connected to the battery. If after replacing the battery and alternator it is still reading 12 to 13.5 volts, it is not working and the light will stay lit on the dash. You may have purchased a faulty alternator if the system tests out this way. Have your system checked with a volt meter or load tester bit be sure all the connections are proper and clean.

Check that your rear interior lights shut off. Other than that disconnect the + Battery cable and put a voltage meter between the two. Pull all of your Fuses and replace one at a time checking to see if the voltage changes, this will show you where your problem is.

sounds like you know what you are doing...
Kudos for at least trying to fix it yourself anyways!
Charge the battery and sell it... lol

start the car. if you have a volt meter at the battery you should have 13 to 14 volts while running. if not your alternator isnt working.

quick check is to remove a battery cable while the motor's running. If the motor stays running when you pull off the battery cable, the charging system is functioning properly, if it dies then there is a problem with the charging system. Don't leave it off long, as this test is stressful to the circuit. You can test the voltage regulator by putting a volt meter across the battery posts to verify voltage. A fully charged 12 Volt battery should show slightly above 12 volts DC. With the engine running and the volt meter hooked to the battery, the charging system should be showing around 13.8 volts DC.

voltage regulator is broken (alternator) change it our gonna fry another battery symtom head light flash dont drive like that change the alternator hope it a fixya thanks pierre

The most likely problem is your alternator, but you can check with a volt meter to ensure that is your problem. Start your truck (use a battery charger or jump to start it if you need to) and put your meter on the battery post's. If your reading 13volts or so your alternator is working and maintaing voltage, however if your reading starts dropping to 10 or less(may take a few moments to drop) then it's probably your alternator. You can also check your battery's voltage before starting your vechile, if the voltage increases after you start the vechile then it seem to be charging. Alternators can be repalced somewhat easily, it's only two bolts however you do have to remove the fan belt, and re-route after installing the new alternator. If you have some expirence working on cars you can do this yourself in your driveway.

Hope this helps
