Just trying to figure out want is going on with my headlights. I changed them both because one had blown. A day or two later one off the new globes had blown. I have checked all the fittings and fuses but still blowing globes out!

Any thoughts on what is going on?

Hello,

Yep, it sounds like the alternator is overcharging the system. Here is a guide to help you confirm the issue:

Should not have more than 15 volts.

Please run down this guide and report back.

Cheers, Ken
