Post subject:  Electronic Voltage Regulator Wiring Help
Hi need a bit of advice on the wiring diagram printed on the top of an

aftermarket relacement voltage regulator.

My car has had the three pin regulator loom connector dismantled, so I have

three loose wires with spade connectors on it,so the connection to the

regulator is not foolproof!

I have itentified what the three wires are i.e. 12v.pos,earth,and exciter to the

alternator.

Looking at the TOP of the box the markings are....

/ D+ D- DF\ reading left to right,so....... if I want to wire it up useing my

3 seperate wires do I look down from the top and connect to the pins under

or do I turn it over and use the markings on the top while looking at the bottom

The reason I ask is,I have connected by looking from above and this blows

the fuse with the exciter circuit in it,i`m pretty sure it`s fried the regulator!

Sorry to ramble on so much!

I have got a loom with the plug intact but its miles away!!!

So can anybody tell me the wiring positions when looking from below with the

middle horizontal pin at the top

Thanks Andy

Andy,
the diagram of the connecting pins should be read exactly as it is appears, not as some sort of 'X ray' view... :lol:

Sorry, can't manage a diagram with the (horizontal) earth pin at the top, but is this any good?

Exc. I _ I +ve
...... -ve

Thanks for that,I am amazed that you could understand my ramblings! :)

So that means I have had the exciter and 12v pos mixed up :x

Next question is will the alternator be ok?

I am resigmed to having fried the regulator.

Andy,
that reg may be ok as long as you had the earth lead correctly placed on the horizontal middle lug

all you can do is test it, alternator will be fine

I`ve reconnected the regulator the correct way,and run the engine.

Checked with a meter and the alternator is working...... but no regulating

is taking place as the voltage just keeps rising with the revs up to about

17 volts dropping down to about 13 volts on tickover, so looks like the

regulator is no more :( ah well.

Thanks to everyone for your help and advice,god I love forums :D

ive never exprerenced a non mechanical one, i like the mechanical one, as i was over charging slightly, so half aN HOUr read with mr haynes manual and i had adjusted it to correct voltage!

Thanks for the offer Sean,how much do you want to put a couple in the post?

The car came without a regulator,then I found a spares car for £100 but guess what about the only part missing off that was the regulator :x
