Hello,

After working on a led mod in my viper night drivin' something stange happend.

I plugged in a led light in the spare 12 v plug inside the cabinet. Most sega machines have this.
I never had any problems with the led mod before but during some moving of the lights the speaker made a hard hummingsound so I shut down the machine right away.

I removed the led and turned the machine back on.

Now the sound is not working and the 12v plug now only supplies 10v!

Were should I look to solve this problems? My boardskills are limited but everything looks ok.

Hope to have this working soon.
Greetings,

Ok, did check the led wires and I crossed the wires so I think I short circuit it.

Would this blow of fuse???

Could it be that a bridge rectifier has gone bad?

Any suggestions would be welcome.

Good weekend,

Bas

Hi, they are 12v blacklight leds. They work perfect with the space 12v plug .....until I crossed the wires):-/

Ok it was a bridge that needed to be replaced it now works perfect again.
