Replaced NSS switch/wiring.ballest resister.voltage regulater.alternator now what???

Found the bulkhead connector.... will look at it tomorrow. I was also going through some parts I had laying around and found a light switch for the cluster in pretty good condition. I removed the cluster and saw that the old light switch was pretty corroded and moist so this maybe the cause. I will switch it out and let you guys know what happens. Thanks everyone for the input.
