Picked up and completed initial assembly of this trem, and noticed an issue immediately after setting resistor from TP 1,2.
Moved on to the next test points, and nada.
First issue seems to be lack of continuity on diodes immediately south of the relay, and the bypass/tap switches.
Switches are good, and pots have proper sweep.Downloaded the help guide and am now probing a few voltage points..
while I am well versed with troubleshooting in my work life (server technician, also did years of access control and RS485 stuff,) this is a little different.Is there a suggested order to proceed through the voltage checks? Just a simple R to L across the board?
Too tired to rip the board out of the enclosure tonight, but will print out, laminate and start checking this weekend. So far though, not seeing any bridged solder pads, or cold joints.
Not my first rodeo, but for sure the first with ICs that are this particularly static sensitive.Thank you all in advance!
Jason,
I wrote the troubleshooting guide to be followed from step 1 onward. …as a flow chart of sorts as you answer the questions. It’s probably not the best course of action for troubleshooting, but it’s a starting point. So based on your symptoms, hopefully there is a point in the guide that will deal with that problem. The voltage chart is for reference as the troubleshooting guide directs you to measure certain points on the board.
Let me know if you have questions.
