Where is the Relay for...?

I lent a buddy of mine my Hayes and and Mazda OEM manuals. So I don't have them with me for easy reference.

My turn signals and Hazzard lights are NOT working.
I checked the fuse (METER-BACK), and it appears to be fine.

I am hoping it is something easy like a connection or relay. I don't know if it was damaged at the track (when my clutch exploded) or later. It used to work when I street drove it.

Where on the body is the occilator or relay which controls them?

Any hints or short-cuts? I just want to get a a jump on repairing it, and finish breaking the engine in on the street.

Thanks

'79-80--to the rear (towards passenger compartment) of the CPU, on a bracket with two other relays.

Did you check the hazzard fuse? The relay turn signal/ hazzard is in the cpu. The cpu is a fairly large black box directly behind the fuse box. There is a large 17 pin connector that plugs directly into it. The nuts to get the cpu off are a little hard to reach. I found it easier if you remove the fuse block first. It will make access to the cpu a lot easier.

Not yet. I will have a chance to work on the car tomorrow afternoon. Hopefully I can isolate the problem.

So you're saying the occilator for the Hazzard lights is behind the fuse box?

Basically I am saying first check the hazzard fuse. If that checks out, the cpu (which contains the flaser relay) is located directly behind the fuse block (under the dash, I am not talking about the fusible links). This is for your SE, correct?

When I blew the hazzard fuse once, I did notice the blower motor for the heater and the clock were both tied to this fuse, so if these are working, then it probably is not the fuse.

Good luck.
