That's very interesting Rog thinking

It got me thinking, so I've just mentally ticked off everything below:

Which confirmed all the circuits on that connector that I would expect to be working, are indeed currently functioning correctly on Monty.... with the help of a 7.5a fuse wink

The remaining circuits I would not expect to work are the aircon lamp as I don't have aircon, and anything ECU related (PATS LED & ENGINE MANAGEMENT LAMP) as I no longer run the Ford/Visteon ECU. This also tallies with the three circuits I lost when the 5a dash module fuse blew (fuse 4), as we know I was able to reinstate these three circuits (and the speedo) by replacing the 5a fuse with a 7.5a fuse.

9. Handbrake/Fluid switches

13. Ignition lamp

15. The ground

The above three circuits (and the speedo) continue to function perfectly with the 7.5a fuse fitted, but the continuous blowing of the correct 5a dash module fuse under the dash does seem to indicate the resistance, and therefore the load on one of these three circuits must have recently increased.

However, I'm also now left wondering if the following six circuits I've lost are even protected by the 5a dash module fuse (fuse 4), or any fuse at all for that matter!!!!!!

1 - No illumination of the fog light switch - Rear fog light still works
2 - No illumination of the heated screen switch - Heated screen may not be working?
3 - No indicator tell tales - Indicators still work
4 - No headlight tell tale - Headlights and sidelights still work
5 - No high beam tell tale - High beam still works
6 - No seat belt tell tale - This light never worked in my ownership

If the above circuits I've lost are not fuse protected and there's been a recent increase in resistance somewhere, then the weakest point in the tracking would indeed blow just like a fuse.

The investigation continues, but it does seem odd I can lose the above six circuits without any fuse blowing, are these circuits simply passing through the other 20a dash module fuse (fuse 6) in the small fuse box mounted under the bonnet on the scuttle by the ECU & MFU?

And why would Morgan choose to protect the dash module with a second 20a fuse, surely 20a is way too high to offer any protection to the feeble PCB tracking frown2

I appreciate I've introduced more questions than answers here, but I have an inquisitive mind and the way Morgan wired the dash module currently makes no sense to me, or should I say the way they fuse protected it follows no logic!

Perhaps someone can enlighten me confused2
