Re: Starter issues
I have a 69 Camaro and just had a similar problem with my starter. I too replaced the starter thinking it was a solenoid issue but the new starter had the same problem. Then I replaced the battery, but still had the same problem. So I stopped throwing money at it and began diagnosing the problem.
I started tracing the wire from the solenoid going back to the ignition switch, (a lot of unwrapping of tape) remembering that these are nearly 50 year old cars and probably had several owners over the years, I wanted to make sure there were no issues with the wiring. What I found is that over the years this wire had been spliced together three time (crimp type connectors) and that the sliced connections had corroded over the years. I ended up cutting the wire back to the original wire coming off the ignition switch through the firewall. I soldiered and shrink wrapped the new connection which should last another 50 years. (I don't like crimp connections in the engine compartment, exposure to many corrosive elements, they tend to fail over time from the elements and vibration and crimp connections are not sealed well)
I decided to take it a step further, understanding that most of the electrical components have been under a great deal of amperage which causes heat from the bad connections I decided to replace the ignition switch and the neutral safety switch which completes the circuit and are all parts of starter connection when you turn the key. This still gives me pause as to whether to put in all new updated electrical wiring, but I will put that expense (est. $600.00) off for another time.
I will tell you that my car starts like a new vehicle and I no longer worry whether to drive my car somewhere because it might not start when I get to where I am going. Now the starter sounds the way it sure sound when I crank the starter (I think most people know what I mean by this) and I have taken the car out everyday over the past 5 days on numerous trips to the store, for long evening rides, long rides in 85 deg weather to dinner... absolutely no issues.
BTW: I used a voltmeter and a test light to verify voltages but unless you can measure amps you may miss the problem that I had when the line is under a load. The wire always showed 12 volts, what I could measure was the lack of continuity in the wire when the starter was drawing a full load on the solenoid.
Good luck, take your time it will be worth it once you get it fixed.
