I'm still trying to figure out why I don't have a tach. Now I'm looking at the OVP. Is this normal? Thanks

1st: ignition off. Power at the #1 OVP socket

2nd: ignition off, OVP plugged in

3rd: ignition off, power at the ECU plug

4th: ignition off, ECU attached, light on the OVP fuse goes out.

5th: ignition on, OVP fuse light comes back on

6th ignition on, ECU removed, fuse light on, no power at ECU connection
