Default Hella intermittent wiper control FIXED

Robert Wilkenson came up with this test method to determine the correct wire that would do the delay:




Leave the Hella off, test on Low speed to start as it gives more time on each sweep.

Remove each wire and note which ones stops the wipers - then touch it back onto its pin.

Does it just move a little ways or finish that sweep? Looking for the one that finishes the sweep.

The Green wire across from the Black on the switch is the ONE.

It stops and finished the sweep on both Low and High Speeds.

I hooked up the Hella wires to the Green wire and its pin and its works on both Low and High Speeds plus it Parks.

With the Hella switch knob in off, it works normally. To work with a delay, the Jaguar switch is set to the desired speed and the Hella switch adjusted to the delay desired.

Happy Days are here again... on to the next project!

Good Deal, Roger!
There's nothing quite so frustrating as something that Should work and simply won't.
I'm glad you got it figured out.

Default Yes, my lucky day

I picked up the aluminum radiator support that I had to modify to allow fitting carbon fiber air box with K&N filter.

The guy doing the welding/cutting of the new piece I bought... did a Pro job of the welding and even polished the whole thing.

Looks wonderful... now I only have to make a paper template of the Jaguar contours from my S3 version and cut them out and file down the edges.

Should look great! Pictures show the before piece and now modified one that is so shiny in the photo it is hard to see the new upright rectangular piece... I modified the mounting plate before the work was done to get rid of the outer upright piece and will now mount the trans cooler down lower. Need that space
for the custom made carbon fiber cold air box to lay and the K&N filter to fit there.

It is a great day...

Hi Roger,

Did you ever put together a wiring diagram for this switch? I have one in my '66 Volvo 122 but my Jag is currently my daily driver and I'm thinking about swapping.

Thanks,
Adrian

I found a old document that shows relay connections:

Black to 53M
Red to 12V
Black switch to 53S
White to 31

If this in not enough, let me know.. Still have the Jaguar and original Hella box.
