Bought a replacement beacon assembly, installed it, activated multi-ball and nothing. Go into adjustments menu to make sure beacon setting is on and while scrolling thru the menu the beacon starts working without making any adjustments. At first I thought "cool, it works!". But it wouldn't turn off. I turned the pin off and back on, played a game and it just keeps going (when power is on).

I go back into the menu and turn the "police light" setting OFF and it continues running.

Now I'm used to things NOT working, but here I have something that wont STOP working. Is this similar to a stuck-on coil? It's odd that it still runs after turning the setting off. Should I start with checking the transistor or is this a cpu problem? This light connects directly to the power supply (which is new) and the cpu.

Don't know if it matters but the old beacon was smashed off by a punk with a hockey stick on location, possible short?

Thanks!

A couple thoughts.

Does a relay soldered to a small board get enabled to turn it on ?

I'd be sure it hasn't become magnetized, or the transistor that drives it isn't bad.

If the beacon is kind of direct drive from a transistor - check that next.

The beacon assembly - be sure it doesn't have anything wrong which started your problems.

No relay or separate board. I just checked the transistor and it's reading good. The beacon assembly is from Pinball Toppers, it works as it should, the problem is it's getting constant power.
I guess I have to dig further upstream.
Thanks!

Did you ever get a fix for this? I just picked up a LW3 and mine is doing the same thing.

I can't remember exactly what I did to get it working, but I did replace a few bad transistors on the cpu board. I would check there first.

Hey action76 , did you ever get your beacon to start behaving?

Bob, Yes I did get it working like it is supposed to. I want to say I was an IC on the driver board that I had to replace that fixed the problem. If you want to know which one I will take a look at the boards when I get a chance and try to remember.
