@Greg Walton, the MPPT will never output that high of a voltage - regardless of what PV voltage is coming into the MPPT, output voltage will be determined by your charge profile.
There are no user-serviceable parts in the Venus. Have you checked the fuse in its power supply? If you have, and you have absolutely verified that it is good, please contact your dealer for additional troubleshooting steps and/or to inquire about warranty service, though be advised that by opening it you've definitely compromised its eligibility for warranty coverage... that'll be a discussion between you and the dealer from whom you purchased it, however.
Best of fortune!
Hi Greg, Can you post some photos? maybe someone else can spot something.
