10 amp fuse keeps blowing

[RuSSkaja_Bratva]

Hi everybody, I have 1985 Mustang GT Foxbody and ever since I converted my headlights from a sealed beam to an H4 Octane brand, my 10 amp fuse exterior lights, instrumental illumination keeps blowing. The headlights still come on but the parking yellow lights don't.
Any solution to fix that?
Thank you

Sounds like you have a short somewhere, possibly during the conversion you pinched a wire for the exterior lights. Recheck your work and report back. If all is well with that you'll need to check for a short to ground in the circuits.

Does it blow immediately or take some time?
Have you checked circuit with a amp meter to get a better idea if it's a dead short or higher than normal draw or intermittent problem?
