Power Driver board question...
I'm trying to read power output from the power board, and it's a bit of a crowded mess, but I finally figured out where the 50VDC test points are.
Bad news, I'm reading 75VDC across the 50V test point and test point ground. Further up the circuit the way I read it, looks like potentially the bridge rectifier is the next step in testing.
Reason I'm doing this is the supercharger accelerator board's not working and I'm getting ~ 75 VDC across J7.
I'd love to hear suggestions!
Accelerator board J7 power input reads 75VDC (resized).pngPower driver board reading 75VDC from TP6-TP5 (resized).pngI've got more details here. I think I should have just done it all in this post instead of in this forum...

Quoted from red-line:Hey guys, I'm experiencing my first supercharger issue. Yesterday everything worked fine, but today I have problems. The diverter is staying closed, so my ball won't enter the SC. it still gives me points for hitting the SC, but it won't actually enter the SC.
On my test report, it notes to check switches 81-85 (optos 1-3, enter left ramp, opto made loop). It then says that opto 1 is stuck open, opto 2 is stuck open, opto 3 is stuck open, and there is a diverter error.
When I do a solenoid test, the diverter high opens the SC and it snaps back immediately. When I test the "diverter low", nothing happens. Do I just have a dead solenoid? Would that cause the opto issues?
Any help is appreciated
Sounds a lot like what mine is doing - check voltage levels on J7 on your accelerator board, under the playfield, near the bottom.
Quoted from centre-drain:If the opto on the accelerator entry ramp (left ramp opto) does not detect the ball then the diverter won't know when to open to feed the accelerator.
You might just have a faulty opto, with the other error messages it is more likely that you have a faulty opto board or the 12V supply missing from the opto board.
The 12V comes from a header bottom left of power driver board, just measure it on the opto board to see if present.
measure between the grey/yellow and black, should be around 12V. DC
Yes - it's J118 (which supplies accelerator -J7- and opto board), lower-left of power driver board. As GRUMPY explained to me, it's unregulated power so mine was a little higher than 13VDC.

Quoted from wamonkey:I think I got all the errors - switch 81, opto 1, switch 83 opto 3, divertor error, up down map down error.
I am thinking to replace all the optos but any other ideas before I order parts?

I had a very similar problem - turns out the opto board at the top of the underside of the playfield wasn't getting power as lines were cut somewhere in the bundle. If you want I'll post a link of my post here.
Quoted from wamonkey:Please - still working it. It was an import so I expect issues - anything would help. I was planning on replacing optos soon.

Hopefully this one helps you.
