Morris Minor Owners Club

I have a 1960 tourer that i am trying to put the wiring back to original. I have every thing done except the heater hot wire. I have looked on 9 different wiring diagrams. None of them indicate the location of any of the heater wires. I am hoping some one has a 1960 and can tell me where there heater hot wire is connected.

Thanks for your help,

Vigil

Vigil, the heater wires connect to the heater fan motor and it shouldn't make any difference which is hot and which is ground. If you find the motor spins backwards just reverse the wires.

In my experience - they run the same way whatever the polarity. I believe some have reported otherwise - but it's not my experience!

Same for me, but I mentioned it just in case. I think it's just very early cars that this will effect....?

In my experience it's the late heaters that have permanent magnet (polarity sensitive) motors. I've seen it on a 1970 saloon and a 1972 van. They have a label on the motor that tells you which direction it will turn depending on which wire is positive.

Here's a picture of the label on my saloon's heater motor:<br><br>

Nice one Alex - All mine are "mine" production cars

Come on backguys. He is asking where are the wires connected. The general consensus is the hot side is the green side of the fuse box and the return is the earth terminal on the regulator. Was the heater installation documented anywhere to describe the wire locations.

Refer to BMC workshop manual wiring diagram on page N44 items 18 and 19.

Thank you for replies, but I have no worries about the rotation of the motor.

jaekl - Thanks for getting the post going in the correct direction.

Mike - Thank You - That is just what i was looking for as far as a diagram.

Thanks to all who tied to help.

Maybe if you had phrased the question in English you would of had an answer quicker

PSL184,

I thought it was pretty clear from the heading. "hot wire to heater". Then asking about the wiring diagram. Sorry you did not understand. There was no reason for your rude reply. I even said thanks for the reply you made. I guess i could make a rude comment to about your ability to read. There were two other people who seem to understand my question. But i am not that kind of person. In the future please do not reply to my posting unless it is helpful. You only make your self look bad with rude comments.

Thanks,

Vigil

Vigil,
I think he was referring to English rather than American. You know the language barrier. Although, I don't see much area for translation, so looking at the Emoticons, I'd say it was just in good fun.

Yes jaekl you are correct - I was making fun of the situation. But no worries, as requested, in future I wil not bother

If the heater wire is getting 'hot' - there is something very wrong! Take care it doesn't start a fire! It should be wired through a fuse - the Ign controlled fuse - to protect the wiring from any overloading that may make the wires 'hot'.
Also - if you look at Barry's very useful wiring diagram in the 'sticky' just above this thread at the moment - it clearly shows how to wire up everything - with correct colours clearly shown - and which fuse to use ! Well worth printing it off and keeping a copy in the car if you are not familiar with the Minor's wiring.

I do not know the person who posted. I am sure they are probably a nice person. I figured after saying thanks - the response was un called for. Sorry - If my reply was offending to any one. If i was offended i would have used a lot stronger words. i am not here to fight. I only want to get information on my car. I think we beat this subject to death at this point. So lets all just put it in the past and move on.

I am still wondering where the heater wire was connected in the 1960 model. I found plate 44 in my 14 edtion manual. It was not in the earlier edtion. I think it is for newer models. It shows a instrument voltage stabillizer on the line to the heater wire. I am wondering if this was done because the older model were melting wires when hooked into the gas gauge wire. I may be better off running a wire direct to a1 just to be safe.

Thanks again for all your help and comments,

Vigil

It certainly does NOT go through the voltage stabiliser! And it does NOT come from A1 !!! Look at Barry's diagram!!!!!
It could be (probably is) piggy-backed off the feed to the stabiliser - they certainly are light green wires. Wherever you feed it from - be sure it goes through the Ign fuse.

I did not mean the wire was getting hot - i meant hot as in power. That is just what i am trying to avoid. Melting wires

I looked at the 'sticky' diagram. - I did not see a heater connection listed.

I have not really studied the diagrams till recently. At this point i can almost tell you the color & number that goes to most of the devices. Mostly from looking through them to try and find the heater power wire.

I am no Morris expert - I still learn a lot with each new project.

Thanks for your help,

Vigil

Yes, the instrument stabiliser would not be on the 1960 model as I understand it was on the later ones which had a "slow" acting fuel(gas) gauge whereas the early models like yours had a quick gauge, ie gave reading straight away you switched on. This language business does give some problems. We have had a post with English-American conversions somewhere but must admit I don't recall "hot" being there. From your posting I take it to be 12 volt supply, as opposed to ground. Think I've heard the term over here, but only for high voltage or dangerous extremes of radio waves. If you're still puzzled about the wiring, I'll have a look under the bonnet when it gets light.

Plate 44 shows - that 18-26 goes to the green on the stabiliser- The other poll goes to the gas gage/sending unit.

So yes - you are correct - it is piggy-backed off the feed to the stabiliser.
Then goes to A4 - Sorry i put A1 last time by mistake.

Thanks for bringing that to my attention.
