1966 Electrical Questions from Australia

Hi Bill -

I have a 66 Lincoln Continental Convertible. Are you able to tell me exactly what the four relays located in the B pillars are for 2 in Right Hand and 2 in Left Hand.

Thanks,

Ross

Ross,

One is the Window Retract and the other is Interior Light.

Hi Bill -

Another relay question for you. My turn signal lights on the dash aren't working properly and I was hoping you may be able to explain what the four wire turn signal relay dose and how it is suppose to operate.

Thanks,

Ross

Ross -

I've enclosed the Wiring Diagram as well as a Post from our Blog that might help in regards to your Turn Signal issue.

Hi Bill -

Thanks for the info. I am trying to understand how it works, I Already have the wiring diagrams thanks. What I can't understand is how the four wire relay is supposed to work. It has a wire going to each globe on the dash but only receives a signal from the right hand side to flash, I was hoping that you may be able to give me a rundown on how it works.

Thanks,

Ross

The Wiring Diagram that I sent, and you state you already have is going to give you the most information. You will need to follow the path from the Dash Signals, and it will lead you directly to the Relays on the Diagram. You could also begin with a continuity check on the Turn Signal Switch, but it may be easier for you to look inside the two Relays for electrical damage or poor continuity at the contact points.

If the Car and/or Relays were here, we would be bending back the tabs on the Relays and doing just that. You can send the Relays to us for testing - but of course the Shipping is not going to be cheap due to your location. The testing cost would be nominal, if any. We can not put into writing how the components of this complicated system all work. Your issue could be as simple as a burnt out indicator bulb in the dash, or incorrect LED bulbs or damaged or reinvented wiring somewhere. You need to study the circuits and components shown in your Wiring Diagrams and then inspect and qualify the common problem parts as we suggest.

Sincerely,

Bill

1970 Mark Water Pump replacement and other questions...

Hello Mr. Bill,

Water pump replacement. Broke 4 bolts at front cover housing. They seem to be moulded to he housing. Will be removing housing, maybe cutting if off with a multi-tool, to save bolt length for removal of bolts from block. Can removal of oil pan be done with engine in place? Can you mention any pitfalls to reassembly, such as gaskets, anti-seize or thread-lock for bolts, etc.?

Sincerely,

John

Greetings John -

We were sorry to hear that these bolts broke while you were removing your water pump. I personally know how that feels. They may have broken because they were over tightened. The torque on the water pump bolts is 12-15 foot pounds.

The good news for you is that the front cover can be removed without removing the oil pan. The instructions are explicitly shown on page 21-07-10,11 and 12 of the 1970 FoMoCo engine manual. If you do not have this manual, ( we highly recommend these manuals ) we can send these pages to you. When you have the cover off you may want to inspect the timing chain and gears as they will be exposed. Anti-seize can be used on reassembly if you desire but proper torquing is crucial.

You will need the appropriate gaskets as described in the manual as well as a new front cover seal. Let George Miller at our office know if you require the previously mentioned pages. We can easily supply you with the necessary quality gaskets and seals etc. as needed. Replacement correct bolts may be available from our ample stock also. Just to let you know, we at Lincoln Land certainly do appreciate your business. Good luck with the repair.

Sincerely,

Bill

1988 Town Car AC-Heat Questions

Hi Bill,

my mothers 88 Town Car symptom is 1st- no heat (core hoses hot). Blower fan works and all speed selections work.

2nd- a/c appears to work and blow good and cold for a while. About 25 miles into drive and a/c stops working then will return with little or no effect the remainder of her trip home. A few days later she tell me and I drove it about 5 miles and the a/c worked great on a cold setting once again. I am more familiar with GM vehicles that actually have a button for the AC. These cars are more of a selectable climate which automatically turns on the heat or the AC depending on your temperature preference. I could not get the heat to work and it has not since she bought it approximately a couple years ago. We live in Florida as well and this hasn't been an issue but I would like it to work correctly. I'm going over to double check vacuum lines and I read a few posts from other people were you have made recommendations. Her main concern is the air conditioning. It leads me to believe this is vacuum related or a vacuum related solenoid possibly or even maybe something to do with the automatic temperature sensor. I know there are solenoids and sensors under the passenger side dash and behind the glove Box but I do not have technical information on how each of these devices work. Please help, thanks again for your time.

Sincerely,

Sean

Hi Sean -

That system is a fully automatic setup except for the control of the air and heat outlets. The operation of the automatic section is complicated enough however that a proper manual is very necessary to understand how it operates in order to do the diagnosis. Checking to find out if all of the vacuum lines and everything else is attached correctly is a good start though. For instance if the aspirator hose to the sensor assembly has fallen off, the unit will cool for an extra long time and then revert towards the heating side and appear to have stopped working.

If you have no proper manuals and would like the automatic climate control section sent to you, we may be able to arrange it for you. Send your Lincoln Land customer number to George at our office and he will get this out to you asap.

Sincerely,

Bill
