Replaced factory cluster w aftermarket. Turn signal issues

I'm with Redfish. Either you made a major mistake in wiring which never should have been disturbed in your conversion, or you have grounding problems with the front lamps

Often a flasher will change speed dramatically between low or charged battery and or when running and charging
Thanks all for the replies and helping me track this down. I didn’t change anything out front but I can check grounds there or add another if needed.

I did just check with the engine running and you are right. With the car running both indicators still come/stay on with the headlight switch on. But the signals do flash faster.

Which is odd because with engine off and light switch engaged no blink at all. Either with the indicators or the signals themselves.
