Mid 70s dodges catch fire-REASON

I have had my second 77 dodge catch on fire due to bad grounds.I have been to several electric shops and this is what I learned.Dodges from about 74 to 79 had a problems with lights,but a bigger problem with grounds.I found on my M883 that I was rebuilding,it was already was missing a few small grounds,some broken others left off as the truck had been worked on thru the years.My main ground to the frame came loose and it seems my electric system went south looking for a ground.If it was electrical, it was ruined.All lights,gauges,radio,batteries,ect.I fixed the problem by running new 10 gage ground wire from body panels to the frame.All battery cables and grounds in the engine compartment was converted to # 2 weld cable. When I started the truck I still get 18 volts to the battery.If I remove the red wire to field it drops to 12.4,but doesnot climb as power is used.I was told to change the amp gauge[since the fire it shows discharge] and that will fix it,any ideas? Does it matter which field wire goes to the front on the 140 amp alt.I now have the green wire to the front and the red wire to the rear.Any info appreciated.Im out about $1200.00 so far.Thanks RR
