Tonight me and my friend were going over his newly aquired lt1 and we noticed that there was some wires that were spliced that lead to the ac compressor. well upon further inspection we noticed that they were beginning to break at the splices(crapy crimp connectors) so we snip them and get ready to solder and heat shrink them but one is to short and its leading into some heat shrink so i begin to cut open the heat shrink and notice that there are small diodes spliced into the wires. so we try to remove the heat shrink and realise that it has a gummy resin in it that has to be straight from hell as neither of us could pull the wires and diodes out of it. so we decide to recover it i heat shrink and go ahead and solder the wires the best we can. Now my question is: Are these diodes susposed to be there? i dont rember that peice of heat shrink being on my ac system when i deleted it out of mt lt1.

 

From the factory, the harness leading to the A/C Compressor has a diode sealed in epoxy approximately 16mm up from the connector. It is used to shunt voltage spikes from the clutch. If you delete the AC, you obviously won't need the diode.

 

i deleted the ac on my lt1. my friend is swapping one into a 3rd gen 91 z28 and he plans on keeping the ac . i was just wondering if it was right becuse i didnt rember it on mine. with the way the wires were jerry rigged on this lt1 i didnt know if some redneck just found some peice of wire to splice with.
