Hey, yea Jason, all voltages are correct now. I posted this before speaking to you on FB. I appreciate everyone's input!

Im the guy!

Anyone know where to start on this? Worked yesterday, turned on and its repeating sound effect and screen went blank. see here: Problems

Finally got my Tempest restore working but some issues. I have Jason Kopp tempest board and IM wondering what that runs under load? I tested the 5vdc on the power board disconnected and was getting 5.3v. When I connect the board Im getting 3.8v. Reason I even checked is because Im getting some...

I bought a new harness for my Tempest restore. There are 4 wires zipped along with the two that connect to the volume pot. What are these and where do they connect?

Can anyone tell me the part numbers to these two connectors and where I can order them? I ordered the 15 pin Molex but it is not keyed like the Atari one so it doesn't connect. The other runs into the coin door. Thanks!

Thanks!

My AR II Tempest board doesnt have any of the test point "Lugs?" installed. I would like to run a 12v fan off this board as well as for testing voltages. Does anyone sell these that I can add to my board or have a solution? Im a newbie and every video I see testing voltages are hooking up to...

Alright running new outlet plug makes sense. That being said, couldnt I just buy a cheap 120v to 12vdc transformer to plug into the outlet and run my fans and LED marquee? That would seem to streamline this whole thing?

So your saying if I add an additional Molex to the empty spot on the block, and bridge the wires from the 120v Molex to the additional Molex I should be good to go or is that a bad idea? drew some lines on my pics

Is there a slick way to tap into a 12v or 5 vdc line? I am only familiar with very basics with all this, thanks!

Any reason the 120v fan would be bad? Seems the easiest route without tapping into any other lines? Guessing noise?

I want to add a powered subwoofer to my Tempest cab (output from Arcade Jasons board) and a 120v fan and need to know if this is a good idea to add an outlet in the cab? Can I run the power cord into a fuse block like the one pictured and bridge, then from the block running to the new outlet and...

I bought an empty tempest cab that has the monitor but no power supply, PCB or amp board. I think Im going to pick up Arcade Jason's tempest multi board. Question is, can I get a modern power supply and which one? I found the amp board on Ebay. Is there anything else I would need outside of the...

You were right, the shifter was set to automatic! The restart/reset still continues. Does it only once in awhile now. Voltages seem to be correct. Tested everything you had mentioned earlier. Is there anything else I can try or should I swap the power supply again? Seems odd that I just put a...

Worked for a year and started to reset again. Checked the power source and it was at 4.6 and 74LS04 IC was the same. Adjusted Power source to 5.12v which is a bit high but Im getting 4.87 at the IC? Seems to only do it off and on but now I noticed my shifter stopped working. Did a diagnostic and...

I am replacing a couple rusted chips that have come undone but need to know for sure if these are the same? Its from a Donkey Kong PCB. Thanks!

Went through the entire sound board, checked all caps and found 2 with incorrect values. I replaced them and still the siren continues Went through the entire sound board, checked all caps and found 2 with incorrect values. I replaced them and still the siren continues. I've read many posts...

All the sounds work. The jump and run sounds seem exceptionally loud and the constant siren sound remains. This is pretty loud considering the volume is pretty low. The volume knob does work.

OK Ive got "Sound"! Only its just a siren sound that wont stop! After I replaced the faulty resistor sound is back but something isn't right. Ive attached a video with the sound its making. Siren sound
