1) since I installed a 160amp one wire alternator, I have 14 volts at my fuse block. Is this ok ? seems like I'm having issues with my electric gauges... 2) I have my temp gauge plumbed into the t-stat housing behind the t-stat, will it be better to plumb it into the intake instead ?
14 volts should not cause any problems for the electrical system. now if you have some component or connection that has excessive resistance, it could act worse with the the higher voltage. usually 13.5 to 14.5 volts is the normal window for alternator out put voltage. what is the issue your having with your gauges? you shouldnt have any significant problems with the temp sender being right after the t-stat. most t-stats have a small by pass or bleed hole in them so the liquid right after the t-stat should be really close to the temp of the liquid before when its closed.
My gauges stop working, sometimes they go crazy and rapidly change from one reading to another... I double checked the conections including the grounds... Gauges worked perfect until I updated my alternator to a one wire... Maybe three years is the limit on summit didgital gauges, I'm really concidering changing to machanical gauges...
ok i was thinking you were using the stock gauges. aftermarket gauges usually will work with the higher voltage but you can never assume that. i would call summits tech line to get the answer. if it is too much voltage then the correct resistance resistor should allow them to work properly. another thing that could be happening is that the new alternator may be putting out a dirty signal that is messing with the digital electronics of the gauges. an easy way to test for this is to put a volt meter on ac voltage and check for any ac voltage. it should be under 1 volt ac. if its more than that then the alternators diodes are not doing their job.
