Tonight I just aint having any luck. I ordered a autometer electronic nitrous pressure guage, and when I hooked it all up and turned it on it jumped to 16psi and stayed, everytime I turned it on it buzzed and dropped a1/4psi till it stopped at 4 1/4psi. My bottle is empty so it should of powered on then went to zero. Any ideas?

The manual it came with said nothing about troubelshooting, I check all the wires to. All it says is unit will power up and buzz, 'this is normal' then it will go to zero.

 

Autometer has a contact form at their website. I needed help with a sending unit for fuel pressure and was able to take care of my problem/mistake with the sending unit through contacting them directly through the contact form.

Although it took a day or two to get a response, but I did get useful info, and then a RMA for them to check out the sending unit.
