I have a magnet that is blowing up TIP 36C transistors.
The magnet will work for a while with a fresh transistor and fuse in, but after a short while, it'll take out the transistor.
Any ideas on where to start with this? Thanks in advance!

These transistors also don't fail shorted on. They check fine (similar to those around them) but just don't work..
What's the resistance of the magnet?
How does that compare to the resistance of a similar magnet? (or what game are we talking about here?)
had a similar problem once before and ended up being a bad magnet core. It was internally shorted. Maybe you have a similar problem.
I know that is not much help for trouble shooting.
Thanks for the suggestions. I swapped out the magnet for a working one, and it instantly blew the fuse as soon as the magnet activated. I'm also getting a blown fuse for secondary flasher, which also powers the motor for the ringmaster.
Quoted from FreeBee:Could it be the wiring harness leading to the ringmaster? Maybe inspect that one.
This is looking like a reasonable culprit, as the magnet and flasher fuse both were blowing. since I've disconnected the ring master harness, neither have blown.
Ringmaster harness is a rite of passage! Pull it out of there, splice the frayed or worn wires, run it through some fresh heat shrink tubing.
Checked the harness out with a meter. There was no continuity except across pins that should have continuity. This was tested in the Ringmaster down position, which is where it is when the fuse blows.
It seems to have been the harness. I ripped the old one out, made up a 'quicky' one, and tested it out of the ringmaster. Worked great. I'll do up a real one tomorrow and install it.
Thanks for the help!

My ringmaster recognizes to turn on magnet in magnet test but does not actuate.
off hand does anyone know the proper magnet resistance
I have 1.5 ohms at ringmaster if this is correct then I am going to purchase longer leads for DMM and continuity test the 4 pin harness coming down out of the center of him like johnwartjr suggested.
also have backbox popper (cannon) not firing properly. This is likely separate issue I will check next.
1.5 ohms seems way too low. I do not know the correct reading for the RM magnet, but I would think 10-30 ohms would be more like it. My ringmaster also had broken wires in the harness when I got it.
Ok thank you for the input. Last magnet I tested was on goldeneye and that one was 4.5ohms and was suppose to be. I cannot find any information online or in manual on actual value.
I now have popper in backbox working again.
I also found F114 4A 250V slo-blow was blown.
Currently looks like ringmaster magnet and up post not working (sideshow) not working at all.
I will have to look into it more tomorrow. If anyone has more input on this please do not be shy all ideas are always welcome.
