all new gauges, now alt wont charge

89 bronco II, internal regulator

ok, i got all new auto meter gauges, speedo, tach, volt, water temp, trans temp, fuel pressure, fuel level, oil pressure. I took out the old gauge cluster and took the factory gauges out of it, put a piece of aluminum there and put 2 small gauges and the speedo, tach there. well i've been driving to work the last few days while i've been working on my gauges. I dont have the factory or any gauges installed, figured it wouldnt hurt nothing. the problem is that my alt stopped charging, i got it tested and it charges fine, got battery tested also. i put the factory gauges back in so that i could moniter the voltage untill the weekend came. well it seems that it charges fine when the factory gauges is hooked up, soon as i take it out then it stops chargeing. wtf would the gauges have anything to do with the alt chargeing

That looks sweet, what diameter gauges did you use? They look like the 3 3/8" and the 2 1/16". I am planning do something similar on my 95, but I posted my thread in the interior section instead of here - doh!
