Hello all,
I'm hoping for some advice on the charging system on my Chummy project which I'm now not able to get charging.
I've previously had everything wired up and charging correctly, and the dynamo has been refurbished. I had the wiring removed to work on various bits since then, and having now wired it all up as it was previously it is not showing any signs of charging, so I'm trying to work through the system methodically, starting with the Dynamo.
I know there's a lot of information on charging systems already out there, but I've managed to get fairly confused by it all. Is any able to explain in very basic terms how to test if my dynamo is charging, preferably without removing it from the car. I have both a digital and an analogue multimeter.
Below hopefully is a picture of the top of my dynamo showing what I'm working with:
First question, is how do I identify which terminal is SH, and which is D?
And the second question is what/where do I need to bridge in order to see if it's charging? The car is negative earth, so do I just put the multi meter between each terminal and the battery's negative earth post in turn to see if there's an output for each circuit?
Apologies if these are basic questions, but any help would be much appreciated!
