trailer wiring question

[comanche32]

hey guys I recently hooked a 4 wire flat on my 90 comanche and when I hook up my boat the turn signals flash fast.. ive checked the grounds thinking that might be it but the ground is good. is there a fuse or do I need heavyduty flasher bulbs. thanks. the bulbs are good they flash fine until I hook up the boat.

try a heavy duty flasher -- should slow it down ---

you mean a a heavy duty flasher fuse

I would be checking the trailer wiring before I did anything else.

trailer was rewired last year and works fine on my other truck. I think il try the flasher and see if that does anything. thanks for all the replies
