jrw69 16 Report post Posted April 20, 2020 Now getting ready to change my 3d solenoid. Any ideas on better made solenoids. My last 2 were bought at CJ Pony but don't last. When I turn the key there is nothing. If I hit on the solenoid with a screwdriver handle it will cut the current through and start. The relay or plunger in the solenoid must stick. The battery is fully charged so it isn't a battery issue. I assume it is the quality of the solenoids. My Mach 1 is a weekend driver and local car shows so I don't need a concourse looking solenoid. 1969 Mach with 351W. Thanks Quote Share this post Link to post Share on other sites

You may also buy a new Ford/Morotcraft from the local dealer or your favorite parts vendor.: https://www.rockauto.com/en/partsearch/?partnum=SW7663 SW7663 B6AZ11450B D2AF11450AA SW3 Quote Share this post Link to post Share on other sites

Buy it from oreily or autozone etc so it is warranteed, but it will say "Assembled in Mexico" on the box, and the parts are probably from China. 1 Caseyrhe reacted to this Quote Share this post Link to post Share on other sites
bigmal 225 Report post Posted April 21, 2020 Are you sure it's the solenoid? I recently had similar symptoms and it turned out to be the ignition switch (Key). Have you tried jumping strait to the switch terminal on the solenoid? If it still doesn't start it points t the solenoid. If not, it may be the ignition switch.

jrw69 16 Report post Posted April 22, 2020 yes, new ignition switch last fall and have the same trouble. This points to solenoid since I can hit it with screwdriver handle and it cuts through and starts. Quote Share this post Link to post Share on other sites

dream car 12 Report post Posted April 22, 2020 I don't think solenoid is the issue here. solenoid contain no moving parts , except a magnetic coil. next time when not starting, jump a wire from battery to the ignition terminal on the solenoid see if that works. its more likely a lose wire connection some where.

dcm0123 15 Report post Posted April 23, 2020 Check the ground connection between the bracket on top of the solenoid and the fender. This connects the coil which energizes the solenoid to the ground. Quote Share this post Link to post Share on other sites
jrw69 16 Report post Posted April 26, 2020 Will check the ground, I actually was thinking that could be an issue. Thanks Quote Share this post Link to post Share on other sites
