I have a 86 that had a stock 305 with an electric choke. I recently did a rewire and I'm trying to figure out how the choke is supposed to work. I was told earlier that the choke needs to be wired into the oil pressure switch, which my haynes manual confirmed. I have two oil pressure units: one that is the sender and the other is a switch. The sender has only one post and the switch has two. As instructed I wired the choke wire to the second post on the switch and a 12v ignition hot wire to the other post. My question is this. Is the choke supposed to have power when there is oil pressure or when there is not? Mine has power when the key is on, but the engine is not running, thus no oil pressure. Is this correct or is the switch bad. Another question. Is the choke supposed to open or close when power is applied to it? Thanks in advance for the help.
