"there is a will" but, is there a way

[tphsmith]

its been 5 ok longer years since the truck has been to this point to be put back together, is there a way to check the electrical connections because I have done changes from 5 years ago to today. and I would "well getting antsie" to see head lights working tail lights working electric fan working so on and so on. I have not bought a battery yet and I was wondering if these checks I want to see if like a battery charger could take place of a battery or is there something else?. is using a battery charger a bad thing or it just wont work.

please feed back so I can calm down
