i upgraded to a s4 and later condenser and the linkage for the headlights hits and gets stuck...... if the condenser was back, 1/4" it would clear....

i do see that later cars have a different part number for the top condenser brackets.....

anyone else do this and or know what the issue is. ?

Are you rotating the headlight motor by hand? It can be manually rotated past where it'll normally stop- Here's the 'normal' stop:




If you go past that, you can get the arm to hit the condenser on a later car:




For whatever it's worth, the upper condenser brackets (928 573 101/2 03) for 87-95 are 125 mm long:

i wonder if m motor is going in reverse....... hmmmm

Ducman82

the motor does a complete circle. counter clockwise...... that right? thats when it his , on the way from 12 to 6 o'clock, on the way down......

SharkSkin

Yeah, the early cars spin a complete circle. I put a later condenser on mine and it works great... will run down to the car in the morning and get some comparative measurements.

Ducman82

please do, thank you!

i did a little more searching, looks like some others had this issue as well, but no one posted what they did to fix it.

will l later motor work in an early car? mechanical wise, looks to be the same......

Jake,

I have no idea if you have mismatched components but what I did to connect the thing mechanically was to undo the crank arm from the motor, get someone to switch the lights on [ignition on] and watch where the motor spindle stops- the lights should also come on but still in the retracted position. Switch them off and check to see the spindle travels in the reverse direction. If all appears to be working as it should, turn the light switch on again, the lights should come on- and then switch the ignition off [leaving the light switch on]. The lights should go out but the spindle should stay in the up position.

At this point lift the lights up mechanically and get someone to hold them in the upright position and then connect the crank arm to the motor spindle. If that does not solve your problem then you need deeper analysis.

no, that all works fine. from what i have read, is that the early cars motor does a complete 360, it does not reverse like the later cars. I'm willing to bet the later cars do that, so that they do not hit the condenser. I'm going to go out and check the wiring diagrams and see if the car side is the same.... but ill wait till someone with a little more knowledge about how they works "internal diodes etc" chimes in before i head to marks....

As I recall my early one did rotate 360. Hence my punctured radiator when the arm fell off.

FredR

OK- with you now. Sounds as though you may need to fit the S4 lift/motor and then doubtless the relay is all different and...? Are the earlier condensers that much different?

God luck with this one- sounds as though it is going to take some ingenuity to resolve. Is it possible to remount the motor further forwards? Doubt this could be done on my model but..?

Fred.

Ducman82

Nope. Looks like I'll need to fit the later motor and relay.

Motors mount the same..... Electrics are what will be needed, and I'm to it! Relay wiring will be the fun part. Hope the two relays are physically the same size

FredR

The S4 relay is a bit of a monster- about 3 times the size of the stock 53 type unit & don't ask about the price.

I'd ask Alan if he can devise a smart electrical workaround for you unless you are into that sort of thing.

Ya the one for my 81 is a big beast as well.....

No conversion is ever easy for me... Lol

Here is a vid of my motor making a complete 360:



I've attached a pic of the area to show the clearance available. I must have some intermediate MY condenser, it's only about 23" wide. You may find it easier to swap condensers than to change out the motor. My mounts were the same 125mm that Rob mentioned, BTW.
