If the tractor has an alternator, is it a 12volt system? I installed headlights on it and they burned out immediately

Look at the battery, if it has 3 cells, (caps where you check the electrolyte level) it's 6v, if it has 6, it's a 12v.

The lamps will be marked with their intended voltage.

If you find the lamp voltage to be correct, and they burned out, better check the alternator output with a volt meter. There could be a problem with the alternator or wiring causing it to overcharge. With a 12v system, the voltage should level off at about 13.5 to 14.5 volts at fast idle.

If the battery has six filler holes, it is twelve volt. Since you didn't specify what brand and year tractor it is, leaves a lot of possibilities. If it was originally a six volt that has been converted, the bulbs or lights should have been changed also, unless the previous owner never used the lights. Although it is a bit unusual for both bulbs to pop at one time, if the tractor was originally twelve volt,then you have a problem elsewhere. Just some thoughts.

You didn"t say what voltage the headlight bulbs were. Other respondents are assuming they were 6 volt. Presumably you know what they are since you installed them. Yes, alternators are generally 12 volts. But it occurs to me you could have 12 volt bulbs and they may have burnt out for some other reason??

Most times an alternator is an indication of a 12 volt system so if your bulbs burn out I'd expect to see 6V somewhere on the bulb.

My impression is alternators are 12 volt unless you request a 6 volt. Sounds like yours is a 12 volt alternator, working on a 6 volt tractor.
