New gal from UT here! Need some help.

Welcome from :canada: Nice ride!
Your elec issue needs to be addressed ASAP! These cars are known for elec demons and can literally burn up.
The flickering ammeter is a giveaway of an issue. In my opinion do not drive it until you get that problem fixed. Make sure the voltage regulator is grounded well. Chk condition of all wiring and connections.
Maybe post your question in electrical forum to get more eyes on it.
Welcome and enjoy. :thumbsup:
