First to clarify my abilities; this morning I couldn't even spell lectrishun and now I are one but this has me scratching my head. I put an old Borgwarner 3sp overdrive up on a steel table along with a 12v battery to run jumper wires over to the solenoid to check if it clicked and it did. Later I decided to re-check it and when it clicked I noticed the ground jumper wire was not attached. My thought was the clip must be on the steel table and conducting through the trans case but just for grins I completely removed the ground wire so there was NOTHING on the negative battery post. Touched the solenoid wire with the jumper from the positive post and it clicks. Called the crew over to witness this and a smarty said to put a piece of plywood under the trans (or battery). This stopped the solenoid from clicking. Grounding that much through a plastic battery case???
Funny experiance Having the iron or aluminum case on the steel table is maybe the answer if it goes to ground ? Your battery is made of a materal that normally does not conduct any tension. The in rush of the solinoid makes serial connetion and should be cleaned? Maybe some waterdamp or smudge inside? Eureka , wonders are still happening. Martinius.
Ok. I've been an electrician for 31 years. Maybe this is what's up. One possibility... the in rush of current that it takes to charge up the solenoid may pick it up for an instant and drop out so quickly that you only hear one click. Put an ammeter in series with your positive lead and see if you have a sustained current. I'm betting you don't. It's like when you turn on the water hose with a closed nozzle at the other end. Water flows, but only until the hose pressures up. In the case of an electrical coil, in a solenoid, that may be enough to pick it up for an instant. Hope the explanation fits the circumstance.
??? of Life! Something like that happened to me with trailer lights...on the road in a kinda emergency situation. I don't remember the details, but everything checked out as individual wires, it did not work when connected, but when I pulled the plugs, it worked, but, but, but. I finally got the booster and ran it at the lights directly...kinda worked, but why? I do not know... Got home tried everything under the sun(after spending a couple of hours on the road doing the same thing) and still could not figure it out. Finally ended up putting a full harness in and problem solved...You may ask what problem...I still do not know! It worked when it should not have and did not work when it should have. Scratching my head one and a half year later, rod Life is a mystery, ain't it fun?
