I was wondernig if someone can tell me how to test the B+ on hantarex Polo chassis? The flowchart says I can check it at TP6 which I connected my positive lead from my DMM to that and touched the negative lead the the large heatsink on the chassis but that gave me a 0 reading on one chassis and on another it gave me a fluctuating reading. A push in the right direction is greatly appreciated.
 
I figured I would also add an interesting story. I had a cab which originally came with a Hantarex Polo that was bad so I replaced it with a K7000, the game ran fine but red was very dull. I decided to sell the game and the buyer came by and tried out the game and loved it, we get it loaded up and later that night he calls me up and said the monitor wasn't coming on.

I go out and check the game and the fuse is blown. I check the HOT and VR and both are fine, I then check the diodes in the power section and D19 was bad. I replaced it and the fuse and plug it back in, sure enough it blew again. I look at the bottom of the cab and there wasn't an isloation transformer and what I originally thought was an isolation transformer was actually step down transformer. I don't know how but the game was actually running at my house without an isolation transformer. I put in a spare ISO and the game fired right up.
 
So I got confirmation from Arm123 that I was testing it right. There's something else going on with this chassis, I'm suspecting an open resistor somewhere. The flowchart really isn't too helpful when it comes to POLOs...
 
This is where I was told by Chad to check the B+ on the Polo.
"The blinds man spot to check for b+ is right where the yoke plugs in... Read off one end of the black loop jumper... "
 
I'm still pretty green to the monitor repair game, and I just can't make sense of what was said there by Chad... I've looked as best I could all around the green yoke socket on the board, and can't find TP6. I've heard it's not labeled on the board, so I was looking for the black jumper... just can't find it. There's a black wire jumper on the board, but it's not very close at all to the yoke socket...

I took a pic of the area, can someone maybe help me pinpoint the fabled TP6.

I also was trying to test the B+ at TP6 except sparks flew and I got shocked. I said the hell with that thing and am going to get a chassis from alva for a tv tube I found. I kept having problem after problem with that polo chassis and I recently called it quits. I'm sorry I can't help but just letting you know how much of a hassle it is to work on these chassis's!
Edit: your picture is not in the area of TP6. It is furthest from the flyback directly in the middle. It's like a jumper wire.

On the connector attached to the yoke (that plugs onto the connectors you pictured) there is a black loop of wire. That is the easy way Chad said to check it.
 
Whoa - too weird. Getting ready to swap a K7000 into a Golden Tee I yanked my Polo 25" out of, but realized I need to add an iso xformer. Apparently the Polo doesn't require one! I have the "manual" for it. It's not super detailed. Watching this thread with interest, so thanks for the updates...
