my brother got to of these from the in laws he said if fix one i get the other.so im going to give it a look, heres what i got.the one keeps blowning the f600 fuse on the picture tube board.i did some reading and they say r612 goes open it blows fuse.well i took the board out of other game same thing happens.so i dont believe both boards would have a bad r612 since it doesnt blow in the other game.any one have a thought thanks p.s one more thing on the power supply the 36 vac on bottem of board is only reading 17.5 what cap would need to be replaced or is there a pod to turn up this voltage

Get out the ohm meter and (with power off and game unplugged) ohm one side of the fuse holder to ground. Do the same thing with the other side to see where the short is.

I know if a diode is bad it will blow fuses but that is usually with dc voltages.

I think there is something wrong with the video board and not the game board.

I usually check things with a heat sink or other large parts for shorts.
 
Regarding the 36VAC measurement: how are you measuring that? Each leg to ground? If so, they'll each only be half of the 36VAC. Measure these AC voltages with one lead on each leg of the AC (pins 6 & 7 on J5 in the power brick). The 36VAC is used on the ARII board to derive several DC voltages: +12, +22, -22, & -5.

You other problem is a monitor issue. (For future reference, there's another sub-forum exclusively for monitor issues.) You're monitor is likely either a V2000 or a G05, but it may be something else. Ideally, it would be helpful to know the exact monitor model. If it's a V2000 or G05, F600 is the fuse for the Y deflection coils. It's not the input power fuse, so checking the bridge rectifier diodes won't help here. Check your "bottlecap" transistors (Q608 & 609) in the Y amp for shorts; they're mounted on the metal frame of the monitor. Also check D608 for short. Make sure your yoke isn't shorted internally.

resistor question now

ok my montior is a go5 802.i was a cap on the side of the metal cage that hold the monitor.like a dunny i put the bad cap in one more time to be sure then i fryed r612 resistor this is the replacement part as listed 100r 1/4 watt 5% so is the 100r omhs thanks

I'm afraid I didn't follow any of that except "i fryed r612"

If you mean to ask if "100R" means 100 ohms, then yes, it does.
