Default damn hobbs - help

So matt (madmatt) gave some tips that I am going to try out. Just looking at others too. Any little bit helps.

I have a and a fuel system with a 1 psi hobbs. I hit 5 lbs and still lose pressure. I get a slight increase I fuel pressure and drops off to 55. Its set at idle for 58-59. I am boost referenced.

Testing hobbs, it works and activates my led. My led isn't coming on.

Fp issue sucks.

Very good possibility....Did you get the area(s) to bare metal before putting the screw(s) in?

Ok.

How long is the ground wire? Shouldn't be over a few inches at the MOST. Always keep grounds as short as possible.

Trying to knock out 2 birds with one stone on this one...

So I hit the hobbs again with air compressor and wiggled the wires and tapped relay with fingers. All is well. Hope it works next time.

I have had a Hobbs switch completely fail once and then work again. Was very clear in the log it failed. I wrapped it in heat blanket so it stayed cool and put it down away from engine heat and another one eventually failed as well. Use a RPM/TPS switch for better reliability. Hobbs switches are too unreliable for my liking.
