I recently changed the board connector on a time pilot and ended up frying what I think is some type of coil in the power supply( position L3 in the picture) I cannot find any serial number or manufacturer anywhere on the unit to find a parts list.
Question 1 would be can anyone tell what part number I need for replacement or is it worth trying to fix
Question 2 what would go so wrong that would cause the damage...I'm guessing I shorted something somewhere

Is that the original power supply? Or is it the inside of a switcher?
I'd just replace the original ps with a new switcher..

As they are pretty cheap.. Time Pilots work just fine on a plain old switcher
 
It is a switcher, the game was once a crazy climber that was converted to time pilot(before I owned it) I figured it would just be easier to replace the whole thing unless it was a cheap fix
 
There is a reason why that part burned up.. Prolly would be more of a hassle trying to de-bug it rather than just buying a new one

Yes, but if the reason the inductor fried was a short in the wiring due to the connector work done in the original post... the new one may fry too (esp if it is cheap, and has little/no overload protection).

Find and understand the pinout. Double/triple check your work. Check for shorts between ground and any power supply pin (+5, -5 +12, which ever TP has).
 
What you are looking at is a choke or inductor. What would fry it is too much current, so look for a dead short to ground off that output, or inside the circuit.

I'd replace it with a new one if you can't find a short in the harness. You could have had an internal short - flip the board, and look for the flash marks.

The fuse should have taken the unit out before the smoke came out. Something isn't right with your switcher.

I have checked the +5,-5 and +12 and everything checks out good...no shorts I have another power supply packed up somewhere I will try and find it and put it on and see what happens.
Thanks for all the input guys, I will post my results...hopefully not another fried power supply
 
If your rails on the PS are all good, then you have a potential short downstream.

You need to meter out your downstream loads, and see if any are reading low resistance to ground on the game, or your replacement PS may go the same way as the original PS, and in doing so, transform both

PS into POS.

Go figure.
