Got an LED speaker light upgrade (from Cointaker) for my Elvis but have been having problems with power - keep blowing fuses. Had everything hooked up properly, I thought, using auxiliary power tap port in the front of the cabinet by the power switch, but it made a strange hum when I turned it on, and then I think it blew a fuse. I didn't go any further with that but decided to get a power supply board 12v power tap from Pinball Life for Stern Whitestar. While installing that first verified that I had blown 2 fuses just to the right of the power transistor cooling fins. Replaced those. Verified that I was getting 12V out of it before connecting it to the wireless receiver for the lights. Then after hooking everything up turned it on and I could hear a transient tick come from the backbox which I think was the new power tap fuse blowing. New speaker lights still didn't work. Checked for power coming from the new tap and it was 0 to 1 V. Checked the new power tap micro fuse and found it was blown. So something keeps blowing the fuses proving power to the speaker lights. I did try powering the IR receiver of the speaker lights with a 9V battery and they worked that way.
I looked for obvious bent or shorted out wires on the speakers and didn't see any. I'm wondering if this is a grounding strap problem. I reinstalled both of them, one on each speaker, but in different positions. Could this be the problem? somehow causing a short? Looking for ideas. Unfortunately instructions for these items (speaker lights and the power tap) were either not clear or missing entirely. I attached pictures of both speakers after I added the LED lights and reattached the grounding straps. Incorrect?
