After a brake (always too long) we finally made some progress.
We managed to make/fit all the hoses for the cooling.
But we found out that we could not fit the Brake servo unit while the motor was allready in...
Originally It's a type one E12 with carbs, so the brake servo is mounted 20 cm or so from the firewall.
We had to take some of the hoses of and lift the engine, luckily we could fit it without taking the whole engine out, but..
it hit the intake manifold (see arrow)
so.. we started working on it.
we hit it with a hammer, not too much, but just enough to give it some space.
but 2 mm is not enough we think:
so we grinded a bit from the intake manifold:
but still it wasnt enough, so we also drilled the holes of the bracket bigger, so we could shift the brake servo a bit to the left, now we think its enough:
so we fitted the hoses again + the brake lines. Now we start with the electrical stuff.
We want to use the old connector of the fusebox to the wiring of the B35.
What we found out:
Pin
1 - Black/yellow: starter solenoid voltage
2 - Green/yellow: ignition voltage fuse 1, to combo
3 - Blue: Charge warning light
4 - Green: Ignition voltage
5 - Black Coil to tagometer
6 - Brown/white Temp gauge sensor
7 - Brown/green Oil pressure switch
8 - Green/violet Input power combo relay, fused
the blue cable of the original wires of the M30B28 is connected to a voltage regulator:
Do we need to use it with the new setup, or can we skip it?
If we need to use it, how do we connect the other cables?
other question:
The original motor did not have an electronic fuel pump so we need to install one. We want to use the relais of the B35 harnas:
(photo other forum)
The system main relais and the fuelpump relais are both connected to the wires, seems logical to keep using them.
Which wires do we need to connect to the fuelpump?
Before we mount the fuelpump + and connect all the wires to the fusebox we are thinking of making a test setup to see if the engine works good.
What is the easiest way to make such a setup?
- we connected all the cooling hoses, so we can fill it up with coolant.
- oil is in the engine
- we've connected the wires to the engine, ignition coil, alternator, startermotor and ECU are connected.
- still need to put in the relais of the main system, how do we know we have the correct relais?
- we're still busy with the fuel return line, so we want to use hoses that go in and out of a jerrycan with petrol
- can we connect the fuelpump directly to the battery?
- when we connect the startermotor to the battery, the engine will turn, should it start as well, or are we forgetting something?
sorry, but we are real noobs with electronics, thanks in advance.
