I have an 89 k5 with 5.7 tbi and 700r tranny and i need a wiring diagram for it because the power wire to the alternater is dead so i made a fuseable link to bypass it and this drains the battery when it is sitting and whines loudly throu gh the radio, any help u can give me would be appreciated...thanks

the gauge works well also

 

I posted a pretty good full vehicle 88-98 schematic here Other Post

 

thanks for that, i have that one but it shows a brown wire from the alternator to the gauge and mine is pink with a black stripe, im at a loss so any help anyone can give will be appreciated

the wire to teh alternator plug is for the voltage regulator. It just needs to be hooked to an ignition circuit (IGN on the fuse panel). The original wire is probably broken somewhere...

 

I do have the regulator hooked up to the fuse box through the ign, but my problem is that it drains my battery if it sits a couple of days and it whines loudly through my radio, i have had the alternator checked it is putting out 14.2 amps. Does anyone have any suggestions on where i need to look next?

 

How old is the battery? How are the cells in the battery? How is the electrolyte level? A whine in the radio is generally caused by a ground loop.
