David's Build Thread

[Davidbolam]

took my propshaft down to cps in team valley today and for a very reasonable price they shortened and balanced it. They did a first class job and phoned me after an hour of dropping it off to say it was done......however I should have measured the size required as its too short... Lots of b's and f's in my garage earlier!!!

We get the ones on the busses at work done there asked last time I was there and they quoted me 85 quid so will be taking it down with a load of bus ones at some point

They did mine for 35 plus vat. I asked about a new one but the mx5 fittings are not available. They have a strange flange and universal joints. Looks like I will be going to Rowland's gill to get another one and back to cps!! At least his one will be easier to measure as I can draw around the shiny bit!

I've started trying to lay the loom over my car to identify some connectors that weren't labelled on my loom.

The bit I am really struggling with is the battery end. There positive terminal has 2 wires coming out. One of the has been cut and the other appears to go to the starter motor then to the fuse box. I cannot work out what the cut on is for. There is also another black and yellow wire ( which I am assuming is the negative but the connector looks like it could fasten inside of the positive terminal.

Here is a photo showing these? Any ideas ???


Also......

To the rear of the fuse box there are 2 wires. A white on that seems to com back from the alternator and a black one. They both have rings on the end. Where do these go?

What year is your donor I have mazda electrical wiring books for a few of the years 1993 94 and 95.

At a guess the black and yellow is negative, the cut wire don't worry about it's for optional stuff I think. The black and white wires are for the main fuse I think. Only know that as I blew the mainfuse minutes after handing over cash for my donor. I will confirm that if you give me your car year.

The year is 1991. I have trawled the Internet but only managed to find a 1992 diagram and that doesn't make too much sense.

The cut wire seems to be. The main attachment to the terminal connector?

Do the black and whit wires go in the fuse box?

It's ok I checked the 94 wiring. Black and yellow is earth and the other wire with the grey rubber boot cover is positive. The white and black are the main fuse connections. the main fuse has to be unbolted iirc to remove the fuse box hence why they are loose. So the battery wire goes to the starter in black comes away from the start in black and goes to the 80A main fuse and the fuel injection 30A fuse and the continues from the main fuse in white to the alternator and the ignition switch were it meets the other Black and Blue wire wire from the starter. HTH.

At the battery end, I'm pretty sure the black/yellow one is ground.
The only place the battery+ goes is the main fuse box and the starter motor.
Thick black wire to to starter, thinner one to fusebox.

At the fuse box end the two ring terminals bolt inside the main fuse box, one either side of the main 80A fuse.
Black one is battery+, the white one is alternator output.
It's a bit fiddly getting them in and out of the fuse box if I recall...
There's a little 'door' that opens on the side to help with access.
