Title: SWEP1 neon issued again.
Post by: infinite1977 on June 04, 2016, 01:44:31 PM: Was tinkering with my SWEP1 and the neon stopped working. I have put the neon on a 9v battery and it lights up so I suspect issue is from the two wires underplayfield. (There is no connector as previous owner did a hack job)
Going though solenoid test and nothing
Any suggestions

That's easy.. find what you did and reverse it

The transformer to these is a DC by memory.. make sure you got your polarity correct!

Brown/ white and grey/yellow.

Going by what your saying I think i have blown ic

Post by: Retropin on June 04, 2016, 07:30:22 PM: Whats the IC code? Ill look it up and see if shorting the 12V output would blow it.. be very surprised if that's the case though

Post by: Retropin on June 05, 2016, 10:17:55 AM: Start by putting the game into attract mode and see if neon lights up.. if not, ground the -ve lead(Black) and it should light up. Like most components in a pinball, these will sit high waiting for ground to activate them.

Post by: infinite1977 on June 05, 2016, 10:41:39 AM: Ok there are two black leads coming from the transformer
(I know which one is negative from when I connected it to the battery.)
How do i ground it to activate it exactly

Post by: Retropin on June 05, 2016, 10:46:33 AM: Jumper it to the -ve rail or even to an earth on the machine will do

Post by: infinite1977 on June 05, 2016, 11:16:04 AM: Jumper ed it on to the earth braid. A little spark came out and went to the diagnostics menu.
Still nothing on neon

You jumpered the 12V and nothing on the neon? But it works with an external DC supply?
That doesn't make sense.. you need to jumper the -ve side of the 12V.. if the neon doesn't light up then you possibly have a faulty transformer. But a small spark when you ran to ground says you have a voltage supply so to find the value of this run a DMM to the same wire and other side of DMM to earth braid.. see if you have 12V
