Re: 55 years ago I was given this USAF 54 3100
Put just under 100 miles on it. Voltage stays at 14.2 - 14.5 without fan 13.8 with. I checked across battery terminals with a good meter and its the same. No voltage loss now, Did this cause alternator guy said gauges are not 100% accurate. Another pleasant surprise is seems new alt automatically excites - this being as alt light goes out immediately even with low rpm starts -- no revving needed. All lights seem brighter as well. Does sound different with the plastic alternator fan. Alt guy says these run cooler due to enclosed design. May say I wish I had gone with a all new wiring harness instead of taking the pot head mechanics recommendations to retain the original 84 chassis stuff. What a mess!!
