Hi Guys, This unit will not turn on the B+ relay from the micro at pin 17. The HHS nad SOS voltages are normal so no protection being activated.Pws voltages seem a little low, 15v line down to 13.3v and when I trick the B+ relay on at the micro the voltages all seem to drop B+ at 130 (should be 140?)and 15v at 11.6. any suggestions, this beast has been running me in circles. I just cannot seem to find a correlation between the pws voltages linking to the micro not turning on B+ if protect is not activated. Cust did say set came in on all sides before failure. thanks for the help! Tony Saracco TCS ELECTRONICS 406 Andra Ct.
