I have never noticed until loo

I have never noticed until looking over the wire harness with the engine out, that there appears to be an extra solenoid for the starter of my TR. It is cylindrical about two inches in diameter and two inches long, and was mounted on the right side of the "spine" of the engine. It was secured by two nuts that also hold one of the rod bolt access plates, the second or third plate from the back of the motor. I've tried looking at pics of TR engines and from what I see there should not be anything mounted there. Could this be a "bypass" as the original is bad?

I'll have to take a look,

I'll have to take a look, but I think it's kinda in series with the starter solenoid. I wouldn't be surprised it it's a cheapie fix, do you remember my car also had an electric vacuum pump rigged up as the original cam-driven pump shaft had snapped. Right now the wire harness is laid out all over the floor as I haven't gotten around to routing it on top of the motor. So a pic might not help, but I will try and get one tomorrow. Worst case is the original solenoid is bad...how much can one of those be? It's a Bosch unit of course. I will get the part number and try importtec.com and see what it costs. I just ran out to look at it again. My notes aren't too good on what wires go where. Looking at the starter solenoid, there are 4 connection points. Two blade style male connectors at top and bottom, and two round nut & bolt style connectors right and left. Near the top connector is "15A" in small letters (upside down) and at the bottom connector is "50". Looking at the harness I see that a white w/blue stripe wire goes to the top connector. Running parallel with this wire is a orange w/yellow wire with a round connector and I don't know where this one goes. Darn...I am very disgusted that I messed this up....I normally have very good notes. The bottom connector has a glob of soldier that makes it look like something else may have gone there at one time. I hope all this drivel I'm spewing makes some kinda of sense. Any help is appreciated.

Jeff: HTHs. I took no notes, just pictures. What you see is the starter wiring. The "big" connector is the positive, and it attaches with another small connector, comming from the wiring loom that comes from the other side of the engine.

Let me try again: Also, the wire coming from the other side (round connector) is the wire that attaches together, with the large positive wire, to the main positive terminal of the starter.

I can't seem to upload the picture!!!!! I will try tomorrow.

Jeff: I was able to send the picture of the wiring to you, via e-mail. Did you get it?

Yes Henry...Thank You! I took some pics a minute ago but like your efforts earlier I can't get them to upload. I'll try later.

are you guys resizing your pics to 640x480?

Here's another try at post

Here's another try at posting. Yep! It must have been something we were doing.

Here's the starter, don't know what wires go to what connectors.



Here's a couple of pics of the culprit. Wires coming off this solenoid went to the solenoid on the starter.



This is the progress I've made so far on the motor. Still miles to go, but it is getting there.

Hi Jeff,

yes that's an after market Ford Type solenoid. a common add-on installation on cars that start clicking when hot.

did you resize the pics to solve the uploading problem?

BTW: to answer the wires quest

BTW: to answer the wires questions....

to the large solenoid lug with nut, goes all the hot wires - battery, alternator hot wire, additional solenoid power feed. They should all have round connectors on them to slip on the lug and be tightened in place.

to the push on connectors on the solenoid - you could have 2 or 3 wires - one larger wire from the ignition switch to energize the solenoid from the switch for starting ( this may have been rerouted to the aftermarket solenoid in which case you should have 2 wires left), one smaller wire from the fuel pumps relay/s to energize the pumps & CS injectors for several seconds while cranking, and likely a third wire from the Aux. afermarket solenoid that adds additional voltage for troublesome stock solenoids.

If you have extra wires unaccounted for let us know and we'll continue resolving the issues.

Regards, JRV
ps: the engine is looking great...brand new actually...{

Thanks JRV....I feel lots bett

Thanks JRV....I feel lots better now. About the pics, I'm not sure why they didn't upload. I always resize them....it would act like they uploaded but when I went to preview they'd be gone.

So this is a common "rig up" for hot solenoid "clicking" problems? When this happens is the original solenoid the problem? Hmmm...maybe I should just leave it as it is? I never had any trouble with the car starting or anything. Would a new solenoid cure the "hot-clicking" problem? If so I'll get one.

Jeff,

yes it's an add-o


Jeff,

yes it's an add-on for weak/bad solenoids, however many times the problem may be a voltage drop between the ign. switch & solenoid, and this add-on usually solves that problem also as it's pulling it's +12v's directly from the +12v starter connection....thereby bypassing any voltage drop issues as well.

Regards, JRV

Ya know it doesn't sound l

Ya know it doesn't sound like such a bad idea afer all. Now I'm thinking...maybe wire up the starter factory-like, and if problems resort to the extra solenoid. This of course assumes I'm too lazy to really fix the actual problem ....which I am quickly getting there.

Jeff,
Steve Magnusson over on


Jeff,
Steve Magnusson over on F-chat has found a good replacement solenoid that seems to eliminate the "hot start" problem on TR's...if you search the archives he lists the part number and source. This would keep things looking "stock".

Thanks Dave...I think it was from "Ace Electric" and the part number was 7-851. I'll look through the archives and see if anything special was needed or if it was a straight bolt in deal.

IIRC it was a direct replacement...sorry, I didn't see your cross-post on the "other" site.
