Electrical Fault???

Just introduced myself on another thread but need help!

My poor Tessy is unwell.
Problem started about 4 months ago, had new starter motor fitted but didnt resolve the problem. Basically I turn the key and get dash lights but wont even turn. Some days she starts first time and other times it can take anything from a few turns to half an hour to get going, once running no other problems.
The other day I took her to a garage and starter motor and battery were tested, all ok but guy said that its electrical and he cant help. Shes booked into an auto electrican on monday but i fear this could be expensive?!

Any ideas?

Ignition switch, small lead connecting to the starter all dirty, earth points dirty

Next time it happens wiggle the wires going to the starter motor then jump back into vehicle and try again or leave it till auto elecy comes out

Ignition barrel is the most Likely culprit. There is plenty of threads if you do a search.

+1 ignition barrel
