Sat in the drivers seat reach up above your right knee under the dash the 14pin loom plug for the dash cluster is reachable , give it a push and a “jiggle” 
if that wont make any difference , as has been said above , take the top off the dash pod and investigate that way down 

You will just scare yourself with an oil pressure gauge , save your self the pain …….

Have you tried running a temporary wire from the engine bay to the dash ? Old wires become high resistance internally with constant hot cold and vibration , i had a similar issue with main beam tell tale years ago, ran a replacement wire and stopped the dim confusion  might be worth a try for the sa...

Cheap nasty fuse ? Often really cheap fuses dont blow when they should , but 
Generally dirty ,loose , bad connections get hot , which makes them dirty , loose worse connections and the cycle only gets worse , hotter looser , melted . 

 you could have a chaffing issue on the wire elsewhere ?

 

I changed my DG for a DJ many years ago , ran the DJ on all the DG stuff, apart from plumbing in the oil cooler , didnt change any of the cooling system and it was definitely worth it , better low down grunt and better MPG , smoother and less hard work .  Then I changed vans and bought caravelle wit...

There id no link really other than earth(neg) is there a bad connection taking the power to neg via the circuit? Never came across this one before personally

But have you checked the voltages with the engine running and under load with and without the engine running  Alternator or wiring?      Easy to establish      Take a voltage reading at the alternator ( using the casing as neg )   If you have less than 14v between the alternator output and the casin...

The difference between 12.8v and 14.5v just making the difference i guess 

Either ignition switch or feed to it 

Its a DG , there should be two big (red) wires that go on the same connection( one from the alternator, one from the battery ) and the small trigger wire onto one ( it matter not which ) spade connection 

I think you need someone to help you , unless you have a multimeter and know how to use it , in which case we can guide you through it  without knowing what set up you have its going to be hard to say much more at this stage  normally you would have a alternator triggered relay joining the main van ...

Some were glued , you’ll need a sharp blade and some heat iirc 
its doable, but will add time to the already long job 
 

Big experiment, you need to change the petrol tank

You mean a DH ? VW did that too ……
