You didn't fully explain how you were testing it.
You are the MFD in making the connections. Connecting the load cuts it on.
Try testing the original flasher while you are at it.
Have the hazards ever worked on the donor?
You haven't shown or described how you've wired the car, what lights you are using, etc.
EP27 is the same basic unit with a different stamp on the side.
Novita is in TN. They may respond by phone, but email has the same problems as posting or writing a letter.
The original flasher no longer works, somebody broke it.....
I had all indicator and hazards working with it prior to its demise. It was doing the rapid flash which indicates a dead bulb due to the low draw of the LCD lights, but it was operational. I am utilizing the stock wiring and front bulbs. On the rear, I'm using stock wiring connected to LCD tail lights, simply cut the stock and connected the pigtails.
I performed the three scenarios you've diagrammed. Two test lights, checked that they worked off the battery before and after the test. Checked the battery, reads steady at 12.74. I clamped the positive leads to the battery, the negative to the frame, and am using alligator clips on the flasher. Connections were all checked multiple times.
Scenario 1:
-L flashed both bulbs every time.
-H never flashed once, no matter the build, order I connected the wires, etc. I checked the volts, it was reading around 12 with and without L connected.
Scenario 2:
-L flashes, but only if H is connected to the other test bulb.
-The test bulb connected to H does not flash.
-0 volts at L when not hooked up tho the test light;
-12 volts at H when not connected to the test light.
-12 volts at L when both connected and 0 at H.
Scenario 3
-test light flashes.
This was making no sense to me, dropped a hot wire and appeared to have fried the flasher. I hooked up the EP27. Bonus points if you figured out what I did wrong. The two ground wires was still bugging me though, why would Ford run two grounding wires? Devil indeed, I hooked (edit) them both up to a ground that ran to the frame and to the negative terminal on the battery. I don't understand it, but it works now.
Forgive the grammar, I'm on my phone and editing is unpleasant.
Thanks again MiataV8 and Chuck, I'd have blown my fifth flasher and still be at ground zero without your help.
