I need help?

I have the us coupe service manual but it does not match my jap imported car.

I was tracing the thermal fan circuit and :

the relays seen to be in reverse order in the control box plus

the wire colours don't match on the fan connectors.

I suspect the actual circuit is different as when there should be earth on two adjacent contacts the earth is on opposite connections etc.

I have worked out the relays (1,2 and 3) all work properly the low speed fans work but the high speed does not kick in when it should.

Have suspicion that when they repaired my car a while back (kangaroo) somewhere underneath they cut and pasted the wires as they did replace the radiator support and passenger side guard but that does not explain the fact the colours are all different to the us manual.

Does chris or anyone have any leads on the circuit for the fan control or jap colour codes.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
