I have an '85 FJ60 that I unfortunately let sit in the yard for too long without good use (approx. 1 year). It will crank after a jump but won't hold a charge after running for about 20 minutes. I plan to take it to the shop to get checked out. In addition to oil/filter change and checking the alternator and determining why it won't hold a charge, what items would you have the mechanic check out, replace etc. as a result of sitting this long? Thanks very much.
