2.1 Super Charger not accelerating well and then blows fuse 103. All 3 magnets pulse no matter which opto is interrupted
- The ball did not accelerate well and was blowing fuse 103 on the Solenoid Driver Board after a few revolutions. I worked on it for a while then put the project on the shelf for a few months after getting advice from lots of helpful folks on RGP. I posted results of further testing early last week. I noted that all three magnets seemed to pulse no matter which opto was opened.
- Clive Jones pointed out the problem could be with one of the 2 CMOS chips on the Accelerator board or a LM339 on that board. By checking the optos in switch test I verified the optos all worked fine and there were not multiple openings when I opened any of them with my finger. This ruled out a LM339 So I replaced the CMOS chips U2 (4011) and U3 (4071) (shotgun repair I know :)) *maybe someone could chime in on how to test those CMOS chips. I put the board in and a new fuse and man that ball started flying around the super charger. Man was I relieved. Now the average speed according to the Supercharger time test is in the low 80s.
