My word; that's a deep dive into the cellars. Looking.....

Company service info doesn't recognise this level of detail for the LR model using K1.8. Rover is no more; aftermarket now supports all of those owners.

Turning to cumulative wisdom of those who were here during those days and are still here now;

To our understanding, the connector on the pigtail has three flat pins in a row. It's rectangular in cross-section. It has a moulding with two ribs on both long sides, one side close together, one side far apart (relatively).

Holding the connector with the far-apart ribs down and looking from the wiring side, so seeing the individual wires as they enter the 'back' of the connector moulding,  pin 1 is the RH pin, pin 2 central, and pin 3 LH side.

In that context pin 3 is ground, pin 2 is signal, pin 1 is +12v.

It seems that the centre pin is signal, whether viewed from the pin side or the wire side of the connector moulding. Checking now if we have a view of polarity sensitivity...

It also seems the feature on the cam that the cam sensor sees is a step-up in diameter and a step-down in diameter 180' apart. It looks like a small balance weight, or a flange that's removed over half its' circumference. The sensor sees steel appear near to it, then disappear. The sensor signal will be a spike in one direction when it sees step-up in dia and steel appears, other direction when it sees step-down in dia.

So, if the collected wisdom turns out to be tosh but the sensor isn't fried then the signal will be wrong by 180' camshaft rotation.

Oh, did you perhaps get an engine harness on the donor motor? Guess not, or you'd have looked at that already.

More later...

Yep, all that turns out to be more or less true.

After I consulted the Oracle over the weekend I now have a copy of the drawing of the part from the MG-Rover days, and it's clear that the connector at the end of the pigtail has three flat pins with leads coloured as in midget's message.

Of those, the red lead is supply, the green lead is signal and the black lead is earth.

You might see part no NSC100932 on the assembly; in the drawing that's moulded into the body of the sensor.

Fuel Injection System Update . . . . . .

midget,

As I made you aware, the Holley EFI system you ordered arrived at T&T yesterday.

Porn, er, photos,     later . . . . .

This has taken entirely too long.

Right mount - which I had to clearance in order to utilize the thermostat housing -

Left mount - which I needed to cut back in order to clearance the attachment bolt - which is now an Allens capscrew, because a hex bolt won't fit -

Tack welded - a few more tacks to do - and now to find somebody to do a really good job of finishing the weld up while out of the car, and in a manner that doesn't warp the crap out of them.

Engine's going back to Illinois on Wednesday, where I'll pick up the EFI and start on the harness.

Going with a mil-spec Amphenol bulkhead connector - once I suss out their arcane ordering procedure.

Still not exactly sure how many contacts I'll need - I'll know by Wednesday night, I hope.

Chris;

Murphy's Law applies to electrical connectors, too. Order a bigger connector than you think you need now. The spare pins will be needed someday.

I completely agree.

I also believe that Murphy and Lucas are twin brothers of different mothers.

The upside to doing one own's harness is that I don't have to second-guess someone else's incompentencies - I can faithfully rely on my own . . .

Don't ever assume because it's green that it is the earth.......

Hey Chris, it looks like you could use a diagonal off that vertical rectangular mount tube out to the skirt somewhere to stop it moving around during & after welding.

Won't be welding it in the car - the whole assembly comes out.  But yes - the more I look at it, the less I like it.

Limited shop leads to limited options, but I do have an idea . . .

[Milwaukee Midget]

I'm thinking a pair of swedge tubes with heim joints . . .

[kiwi belly tank]

Yeah it doesn't have to be a welded support but something would be desirable Mate!

Also . . . . .

Progress report

Wednesday brought another foray south of the "cheddar curtain" by the "maven of misanthrope"  . . . .

A bunch got accomplished, notably:

A/   Crank removed from mock up assembly . . .
2/   Welded oil pan was surface ground flat and now mates to the main girdle (ladder) "unsprung" . . .
d/   Motor mounts got melted together, er, finished welded . . . .
z/   Adaptor plate final design print was reviewed and approved for production.    ETA 10 days

And the midget left with header specs and a lead on an affordable fabricator.

Captions need to be added by the "Hawkeye Guitarist" . . . . . . . . .















"Goat Explosion" headquarters in the background . . . . . . .


The starter is finalized as a "JFB" fit . . . .  as I knew it would be.    Packaged ala . . . . Swift Race Engineering, as anyone who has ever wrenched a Swift can attest . . . . . .



Send your comments and questions to this thread, to be reviewed by those of questionable sanity . . . . . er, Sconnie Nation residents . . . . . . .

TTFN,   More later . . . . .

'mornin' . . .

yeah, captions

ahhhh, let me finish the block installation, and I'll come up with some captions.

Took yesterday and today off, my heim joints arrived yesterday, house and garage all to myself.

I'll post up this evening.
