Car is 76 with new late wiring harness. Initial wiring checkout after harness install.
Turn signal on, front & rear run lights flash as intended but signal light on tach just comes on once momentarily. Is this normal, or do I have a wiring issue ?? Well, i tried all 5 of my stash of flasher relays, several showed same symptom of single flash, but 1 worked OK. Now the hi beam indicator bulb works fine but does not show thru to front of Tach, Don't know whats up with this |

The failure of the turnsignal indicator is common in the OEM flasher. See the flasher below on the top right. Notice the relay coil in series with the 49a pin. When the flasher is flashing, the heavy bulb current causes this relay to close and the tach indicator to flash.
The relay coil loses its efficiency over time and the tach indicator may flash once or not at all. Usually it will still flash when the 4-ways are used. I resell the commonly available EP26 flasher which is pin-compatible with the 914 OEM flasher. Unfortunately the stock EP26 does not have any connection to the C/C2 pin for the tach indicator. I modify EP26 to make the C/C2 pin drive the tach indicator. Attached image(s)
