WH20 Topper Lights

[Agentbarry]

Hello all
I recently bought WH20 to add to my collection, runs well except for the waterfall lights in the top. The connectors all seem fine and LED's 1&2 light up on the controller board. Would anyone be able to give me an idea on what is likely to be the fault?
I’m totally new to solid state machines as all i have had before are EM machines.

also my first post here, so hello :)

Any help is greatly appreciated

Cheers

Welcome to AP

You don't say what is wrong with the lights on the topper? Do they come on at all? Stay on? Some only light? None light? More detail is always good.

The lamps used on this board are specials not used anywhere else (161 from memory but check this) - are the correct ones fitted? Are they OK?

A very common fault with the board that runs these lamps is the bridge rectifiers cark it BUT don't go changing things until we get more info so we can determine your fault

The lights themselfs seem to be fine none of them seem to be blown, but none of them work at all on both banks
The topper has never lit up, not even a flicker ><
I have metered out the cable supplying them and that seems to be ok

Thankyou

Bridges is my bet - very common as they run at their full specification, shown here as "BR1 & BR2"

[Agentbarry]

Excellent, i will give it a shot this arvo
Thanks for all your help

  good luck with your board, I had a problem years ago with wrong sequencing ended up being one of the ics, other than that never had any issues with the chase board

[Agentbarry]

Would you guys happen to know the part number for the bridge rectifier? the part number is unreadable on the components ><

Thanks again for letting me pick your brains

 I got the topper running before selling one at the beginning of the year with a blown bridge thanx to skybeaux.

It's a pretty standard 2A bridge KBP10 (1000V 2A) - probably Jaycar part# ZR1350 ($1.95 - 800V 2A) would do the trick and should also fit the PCB.

cheers mate

Thanks for the help, after replacing both bridge rectifiers one bank of lights now works, but it seems their is still more buggered on the board. The bank of lights that plug into J3 still dont work

any ideas?

[Homepin]

Looking at the schematic - power is fed from BR2 to pins 1 and 2 of J3.

Start by confirming that power is at P1&2 - J3

[Agentbarry]

Got it all working, seems that when i resoldered BR2 it was soldered ok on the underside of the board but not the component side. shitty lead free solder. it does not flow well

Cheers again for all your help

[Homepin]

Great news at last - a tip, THROW AWAY the lead free solder.

Simply put - lead free solder DOESN'T SOLDER!

These machines were made with REAL solder and that is what you should use to repair them.

The (bad) health effects of using real solder are massively overstated IMO

[Agentbarry]

Could not agree more, last time i use that useless stuff
