70 sequential turn signal issue

Greetings All!

I think I know the answer to this, but would like a little extra input please. 1970 turn signals have been working great until the other day. I turned on the right turn signal, and it flashed fast, like a bulb burned out. I got out and checked, all bulbs good, but the right signal is flashing so fast it is like all the bulbs are lighting up at the same time. Left signal is ok now. I do have the upgraded underdash relay to “slow” them down so they look/work better. I’m thinking the unit in the trunk??

Thanks for your thoughts!
