as always... you guys are the best! Gimme a wee while Angelo and I'll let you know!

thanks again

Angelo...

here's what I've got...



As you can see I have nothing going into Pin 9 or 14, I am pretty confident I can run a cable from the coil to 9 no probs but what do I need to do with Pin 14?

Pin 14 - forget it, not required on a petrol van. The connector in the photograph splits allowing you to remove or change the wiring sequence. If you had a wire connected to pin 14 I was going to suggest you open the connector block and re-fit it in location 9 and hitch your new wire from the ignition coil to that.....ah well, can't win 'em all! BTW, you seem to be missing the alternator charge wire at pin 11....can't see it in the pic?

Pin 11 was the whole source of our problem in Wales. This was removed by the guy who came to our rescue, he added a seperate battery light and connected that up with what I assume is the cable from the Alternator! There is however a further blue cable that is unattached behind the dash that has 'alternator' written on it that is not doing anything... youve got me worried now, that last thing we need is the thing to go wrong the same as it did last time. I desperately want the whole electrics re-doing as Im sure it has been well and truly botched by the previous owner.

As for the Rev counter, are you saying that I can still run a cable from the coil to pin 9 and it should work or do we need the cable that should have been at 14 as well... sorry if Im slow on the uptake!!!!

You just need to connect from the coil to pin 9 - thats it!

The counter is working all lovely jubley... wey!

The BOD now goes off after about 30 seconds... boo!

Thought it was too good to be true, so is it a simple solve Angelo?

if your van is an 85 model then it would not have had the BOD system fitted or the second (0.8 Bar) oil pressure switch (near the water pump). The BOD system requires two oil pressure switches. Check to see if you have it - (I would be suprised if you do unless the engine has been replaced).

If your van has a single oil pressure switch and you have fitted a later Dash with Tacho and BOD the warning buzzer will sound shortly after you start the engine.

Easy to solve but check if you have a second oil pressure switch located near the water pump. Wether you do or don't isn't a problem but the appropriate 'fix' depends on your reply.

Angelo, Im pretty sure there is just the one (on the nearside bottom of the engine). Cant see any other obvious switch.

Looking at the picture of your edge connector (earlier in this post), I notice you have a wire connected at pin 12. On later dashboards that incorporate BOD pin 12 connects to the high oil pressure switch but you say you don't have a second oil pressure switch. I also notice that the wiring colour codes seem odd from pin 8 to pin 13 and I will need to check my manual to try and identify which year model dash your van actually had fitted at new. (The DOPS system has been found in vans manufactured around mid '85)

OK, if you are absolutely sure you don not have a second oil pressure switch (near the water pump )then you can do either of the following:-

1. Connect PIN 12 to earth and ensure that PIN 13 connects to your oil pressure switch (near the push rod tubes). Question is - why do you have a wire at pin 12 and where does it connect too at the moment?

2. Remove or disconnect the BOD PCB as it is doing absolutely nothing at the moment other than triggering the Buzzer. Removing or isolating it will not stop your tacho functioning. Without the BOD you will need to have the oil pressure LED function directly off the low oil pressure switch (as in pre 86 vans). The BOD connector that needs to be removed is shown below and is left disconnected once one of the mods descibed below is carried out..

(a) Replace the oil pressure led with a 12v type (Available as a RED flashing type or standard red) and place a wire link in the vacant connector in the postion occupied by the resistor as shown below.

(b) Keep the existing non flashing Red LEd and insert a resistor of any value between 470 (min) and 1500 (max) as shown below.

as they say in the trade... 'jobs a good un'!

All done, thanks a million Angelo... I'd like to say I'll return the favour but I think there is probably nothing I know about these old buses that you dont... a beer or three if we ever meet up will have to suffice me thinks.

thanks again mate

oh, I disconnected the wire that was at pin 13 (the red and white one), inlike the others this did not have a label on it so I havent a clue where it comes from, everything seems to be working tickety boo so I am clueless as to what it's for?
