My signals are blinking to fast. Put a heavy duty flasher in but this did not resolve the problem. Any ideas as to what may be the problem?

The flashers are designed to flash faster if a signal bulb is burned out. The easiest thing is to check your bulbs first.

Usually, it's excess current flow through the turn signal circuit. Possibly a bare wire or other ground problem.

It's been awhile, but I'm thinking that the heavy-duty flasher shouldn't be affected by the current draw unless the battery voltage is way high. What's the voltage when the turn signals flash too fast?
