Nothing

Hi Guys...

Well maybe my 74 got the virus, it got somehting..
Last time I started it was about 2 or 3 weeks ago.. started right up.. usually does
My friend came by with some of his tech tools (He is big Mopar guy)
So before he showed up I put the charger on the car... just because...
When he got here and we went to start the car using the ignition, nothing... and I
mean nothing... so I went through and cleaned every contact I could find, and
the car would start using a wire jumper, but not even a remote starter would work..
Today after leaving the charger on the car all night, I tried the ignition, nothing
then I pulled light switch, no light, went and did a wire jump and she turned over..
oh no horn either..
So I know I have a common problem, am I missing something? I don't remember
having the fuse block down, but it is, could it be corroded wire ends?
any thoughts
Best
Dave
