Need help asap. Replaced a factory headunit today. It was a factory single DIN underneath and a tv screen on top. Now it just has a D/DIN headunit. Everything works fine but everytime you turn the lights on it blows the brake light fuse under the bonnet.

There were three wires left on the plug that had the power, grnd, acc and front speakers. One wire is yellow and the other two are black(the black wires run into the same point on the plug) My guess is this is an illumiation wire for the old headunit and the 3 wires have to be joined together to complete the circuit and stop the fuse from blowing.

Need a reply asap. tonight would be good.

Thanks all

Use a test light (if possible) to find the illumnation wire (this will show +12V when you turn the headlights on) then insulate it and dont use it. If it is joined together with the earth wires you will blow fuses all day. Dont even use the earth wires from the aol head unit you are better off earthing to the body (chassis) of the car this will also help reduce the chances of engine noise. NOTE the illumination wire will show an earth when the headlights are off then goes +12V when you turn them on.

If you still have problems go to my website and get my phone number I will be available till quite late.

Good luck.

Leon

      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/
