New defective OVP?

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

Does the light indicate a blown fuse? (On the fuse not the test light.) A 10 amp fuse should be easy to see if it's blown.

UGH. You're were correct. The light means the fuse is blown. For the last 2 weeks I thought it meant power was going through. I didn't mean to buy these fuses but it's all I saw at AutoZone.

Well, I've got regular fuses and they still blow as soon as I turn on the ignition.
