Hi,
Got a quick question.......
Doing a MH build using a Major Havoc conversion PCB, Amp Rack and wiring harness fabricated by Ken Falta.
When power is applied, I do not get the initial "boom" and there are no sounds during game play, all tests show OK.
I checked the harness at P8-3 to P8-4 (unplugged from the ARII) and get about 2.5 ohms through the speaker connections, no shorts there. I even tried disconnecting the speakers and tried one set at a time (upper / lower) just to be sure with no difference in "hum".
I checked P20-8 and P20-9 (SEC connector) and they have continuity to P7-8 and P7-9 (at the ARII) and appear to be OK.
I tried 2 different known working AR II's with the same results.
The board that I am using is a working pull and to be sure, I tried another known good PCB with the same results.
I have never attempted to use a conversion PCB in a dedicated cab and thought that I read all there was on using one in this application but it appears that I am missing something.
Can someone shed some light on my current (one of many) predicament!?!?
Thanks in advance
Jeff
