Looking for help in validating that the pickup assembly in the tank has failed. I've read the articles, and no I'm not interested in pre-mixing my gas. That being said, the alarm sounds continuously when the key is turned on. Disconnecting the wiring to the VRO tank, the alarm stops. I see there's a small metal washer on top of a pin on the pickup assembly, which goes through what I believe to be the float assembly. Seems odd that the washer is metal and not some better flotation device. When the washer sits across the contacts, I get a read across the side arms, and when the pin/wash rises the circuit is open. So I'm thinking the problem is at the top of the sending unit where the wires go in. That circuit it closed in the off position, causing the alarm to sound. Does anyone know if that circuit is suppose to be open or closed in the off position? I'm thinking is should be closed by default, then when oil level is good and pressure is good, that circuit would then open, meaning that the alarm would sound until the motor was running and creating a vacuum on the sending unit. A detailed description on exactly how that unit works would be most appreciated. Thanks!
