new 1.1 compressor blowing 20A fuses
I am a mentor with Team 3329. We had to replace our compressor this year and went with the new 1.1 from AndyMark. It is connected directly to the PCM, but it is blowing the small 20A fuses on the PDB. We've checked the wiring into the PCM, and have even replaced the pressure switch. Any suggestions?

Rule R56 allows the PCM to connected to a circuit breaker the PDB rather than the fused circuit. This will not fix a bad compressor but at least it will not blow the fuse that you VCM and robot radio is connected to.

Two questions:
If I go from compressor to a spike relay to PDB (20A fuse), would it work (no CAN connection)? Would I damage the PCM if I try a 25 A mini fuse? |

Question for you: Did you install the replacement filter that Andymark sent out? The smaller diameter black one that is deeper?
If so, did you cut about 3 threads off of the part that screws into the compressor? If not, the length of that threaded stem is so long that it will bind into the compressor crankshaft. This could be binding the motor so much that you're blowing fuses. Thankfully I noticed this before installing the filter, and after some cutting and checking and cutting and checking, removing 3-4 threads safely clears the crankshaft, while still allowing a nice secure fit to the compressor. |

Thank you so much for pointing this out, we have been getting a few reports of blown fuses in 1.1 pumps and were not sure of the cause until now. We will be sending an email to customers who received the replacement filters about this issue shortly recommending the use of a washer and/or PTFE tape to prevent the threads from interfering with the crank shaft without modification of the filter. |

@OP:
1) Replace the wiring to the PCM, and PCM to PDB 2) Us a replacement fuse from a known good source, or at least a different one, and ensure that it is FULLY SEATED 3) Double check that you are not exceeding the duty cycle of the compressor Per the 'modifying a pneumatic component' discussion. How is a venting filter, which retains/controls/stores no compressed air at all, a pneumatic component? I am confused, please enlighten me. |
