1990 toyota SR5 Pickup 4x4 Problem- The radio will cut-out temporarly when I use the turn signal or sometimes the drivers window will reefuse to go up and then it will work after sitting awhile. the radio will also cut-out when shifting gears and doing anything that seems to pull a load from the electrical system. Alt and battery are new. Thanks

Hiya John.

Welcome to TN.

Have you taken a look at all the relays in the circuit box to see if there's rust that may cause come unintentional crossing? I would also check the radios wiring. Lastly check all your grounds, if they're rusted, clean them out.

The symptoms point to grounding issue since you've already done the battery and the alternator.

take a tester to the power supply, test it and add loads to the system see how its affected. could be the radio itself too..

p.s. mine did it too when i played it too loud. but i have 4 10"s and 3 1000 watt amps.. kills an alternater every 6 months =] and turns out it was because of the battery it turned itself off. and my battery was relatively new as well..
