MS2 getting VERY HOT

Post by n20junkie »

I have a V2.2 board that i installed MS2 on. Im am using the extra code and was bench checking my inputs and outputs. I just had what i thought was a finished setup when i noticed that the center chip, the one you have to modify for dual table is getting so hot that you cant touch it. I have been pulling my hair out and have disconnected EVERY add on wire that i have added, and its still happening.
Has anyone experianced this, did i checked my solder for the dual table? It looks good as far as i can see but something has to be wrong. Thanks

The 48 pin processor? Sounds like you damaged something soldering in those mods.

The wierd thing is that EVERYTHING works, all the outputs, and so far the launch and nitrous inputs. The 5v regulator seems to be hot as well. I undid pretty much every external bit. I dont know if during my debuggins i damaged the MS2 and now its doing this to itself. For now i will run it and finish all testing, and then get a new chip to see if that fixes it. I will heat sink it to help it for now. If anyone more ideas i will try just about anything.
