prosport boost gauge help, always at full boost???

[abovie3]

awhile back i got a prosport electronic boost gauge (doesnt have peak warning) and its never worked. the gauge lights up, does the opening sweep, and then the needle keeps rising all the way to +30psi and stays there. i have it wired so its in the amber color all the time. the white wire from the gauge doesnt get used for this option, here is how its wired:
boost sender-
red wire to constant source (spliced in with red wire from gauge and led to fuse f44, radio)
white wire is to green wire on the gauge
black is grounded on a near by bolt

gauge:
red is spliced in with red wire from boostsender and wired to fuse f44 via mini add-a-fuse
orange is wired to f82 (dash illum.) via mini-a-fuse
green wire is wired to white wire on boost sender
black wire is grounded to near by bolt
white wire is unused due to the option of running amber color always.

there is no kinks/bends/rips in the vacuum line to the boost sender

ive followed the how to and still cant get this thing to work, any input would help.

ive also already contacted prosport about the problem and they in turn sent me a new boost sender, wired up the new sender and still same problem, what gives??

ok so i got the gauge to work, but the radio wont work now. im using the radio fuse for power. the mini add a fuse im using has 2 slots for fuses, when i put the stock fuse in the top slot, the radio works but gauge doesnt, when i put the fuse on the bottom slot the gauge will work but radio wont. any one have any input?

You're only using one fuse per Add-a-fuse? That's why. There are two slots for a reason: you need to piggyback the main fuse with another, like a 1 or 2 amp. Be careful, because those Add-a-fuses are only rated up to 10 amp, so don't go tapping into a 15 or 20 amp circuit.

i got it to work before i read your post kain, thanks though. the genius at autozone where i bought them insisted "you can put only one fuse in it brah"

I take it the VatoZone in your area doesn't employee MIT grads?
