Turn signals, emergency flashers not working Options

[ORANGE2]

Im sorry if this is posted already but can't seem to find it. I have a 74 2.0. My front turn signals come on solid with the turn signal switch, but do not flash. The emergency flashers do not work at all. I checked and rechecked wire positioning on the emergency switch and even swapped switches. I purchased and installed a new flasher relay.. After I installed it they flashed a couple times and blew two fuses. I believe they are positions 8 and 10. If i put 12volts on the output side of position 10 on the fuse block the relay under the passenger seat clicks a few times and then trips my test probe. I've also checked and re checked light wiring at all 4 corners. Is there something else I should be looking for ? any help would be appreciated.

According to the schematic of the '74 turnsignal system, the fuses should be 9 and 11. You mentioned 8 and 10; likely the same fuses.

It is likely the fuses did not blow at the same time as one powers the 4-way flasher when the key is off.

Did the fuse blow when you tried the right or left turnsignal?

Until you find the short, don't use the 4-ways as if the issue is the right or left side pulling the 4-way will not help isolate the issue.

Put the fuses in and with key on, try left, then right side.

Did you do any work on the car recently?

To find the short, inspect the wiring on each turnsignal on the front and rear corners.
