KB boost a pump
Hello
Is there anyway of testing the voltage coming out of the bap or going to the fuel pump? I already have it installed in the rear fender well so I don't have easy access to the BAP

You should be able to test the actual voltage by disconnecting the wire going to the pump, but you would obviously need to have access to the BAP to do that.
If you simply what to verify that the BAP is working (without knowing what the actual output voltage is) you can test it by simply turning on the key and listening to the sound the fuel pump makes when it cycles on and off, then turn off the key, then disconnect the wires from the Hobbs switch and jump the wires via a temporary jumper to bridge the two wires together - to simulate the Hobbs switch in the closed circuit position - and then turn on the key again. If the fuel pump is now significantly louder when it cycles on and off, you know that the BAP is working.
By the way, if you're not already running a Racetronix fuel pump harness upgrade, then you really should be, especially with the BAP.
