Dan and others, thanks for all your help. The machine is now working fine.
I honestly don't know how I fixed it however. After pulling out the entire
bottom board to inspect all wiring and transformer, etc., I found that one
flipper switch wire had a slice in it and that slice was touching the staple
that holds this wire to the side of the cabinet. I fixed that slice and put
everything back inside the cabinet. Plugged everything back in - put a
brand new 1/4 amp fuse in the game and turned it on. The fuse did not blow!
Game booted right up and works ok.
I have no idea if the flipper switch wire had anything to do with it, my
limited knowledge tells me it did not because it's not in the 69v circuit.
However, if it had nothing to do with it, then I don't know what fixed the
problem?!?!?!
Anyways, thanks again for all the help, it's time to play a couple games.

Hi Dave,
please read the inserted comments below.

I have a Solar Ride that has a fuse problem that is driving me nuts. The
69V 1/4 amp fuse blows immediately when the machine is powered on. Here
is what I've done and checked so far:
2. Have tested the power supply board in another machine, it worked
fine. This rules out the power supply board.
More than likely. However, please consider this longshot possibility. In
the other machine, are you sure the 69 VAC circuit is not overfused, thus
covering up some weakness in the power supply? Not likely I realize, just
a thought.
4. If I pull pin 7 out of the connector when J1 is plugged into the
power supply board, the fuse does not blow (keep in mind pin 6 is still
in the connector).
Right, the fuse should not blow. Why? Because what you have done by
disconnecting pin 7 is to open the 69 VAC circuit by preventing the return
of the 69 VAC to the transformer.
5. Replaced fuse block with one that has been tested as working fine.
No difference.
I don't know where to look from here. It's my understanding that the
transformer is good based on some tests I did and the fact that the fuse
is in line after the transformer.
What voltage do you measure at the 69 VAC take offs at the transformer?
Here is a tedious idea. Desolder the leads from the 69 VAC take offs from
the transformer. Splice in your own wires from these 69 VAC take offs to
the appropriate endings (fuse/connectors, etc.) The idea is to eliminate
any bad cabinet wires; I know you have already done this, in a different
manner. See if you blow a fuse now.
My feeling is either the 69 VAC circuit in the power supply is fooling you
(does not seem likely), or the 69 VAC transformer winding is bad (again,
does not seem likely). I am looking forward to whatever further results
you can share with us!
Regards,
Dan
