2004 arctic cat F7 700 electrical problems!!

Howdy, I have a 2004 arctic cat firecat 700. recently ive been having electrical issues. id be riding and then my headlights went out, both high and low beams but my tailights just got brighter as i gave it more RPMs. im thinking its the dc power box or stator? but i bought brand new headlights and after 30 seconds of running i gave it some throttle and the headlights blew out!. I need help please!!

Voltage regulator or a power wire is grounding.

Carbureted or fuel injected? The carb model has a voltage regulator that is different then on the EFI models. The 04’s fuel injected will have the voltage regulator on th end of the driveshaft on the clutch side. It will also have the speedo pickup, check the wiring to that as it could get damaged easily.

The carbureted models will have a totally separate system a black box(capacitor), and an aluminum voltage regulator. Not cheap by any means when trying to buy from Cat. You can prove the wires on the regulator to see the output while at idle.

If the regulaotor shows low voltage at idle, on both the AC and the DC side, it’s time to check your stator. you need to unplug the main harness by the recoil, and test the resistances between the different leads.

If if I had to make an educated guess, I would say the voltage regulator has gone out, but it’s always free to test the stator while you’re in there. The lighting coils on these sleds don’t have very many posts and windings in the design so they get worked hard and can fail.

Check your tail light wiring for the power wire grounding as long haired freak suggests.
