I picked up a Tomar 12 strobe bar and it worked fine up until I last night. THe rear seems to be in "dim" mode, but theres power to the green wire allowing high power mode. The rear also "shudders" when full warning mode is activated. But when I power the orange wire (2 rear inner modules flash) they are full power, no issue. WHen I disconnect the front PS, the rear works fine. Is there something wrong with the front PS? Ive removed it and looked at the wires, nothing appears to be shorting out. anyone have this happen?
