When I bought my '65 Bonneville it had an alarm system that looks like it's been there a while and seems to be working. I just can't figure out how to set it. It has a siren, solenoids on both doors, hood, and trunk, a switch under the dash, blinking light, etc. Prev. owner said it didn't work (he thought) but the 1st time I disconnected and reconnected the battery the siren blasted and scared the #[email protected]% out of me. The closest I can get is that there is a sequence involving the alarm switch and the ignition switch which activates the system but I can't figure it out and my 80yr old neighbor is threatening to set fire to my garage if I don't stop with the siren. Any ideas?
