grinding noise after start
#11
ok theyre literally about a month old batteries so they should be under warranty. as it starts killing itself it does it very slowly it starts going fast and by the time its done its barely turning over almost as if the batteries are dieing

if i take out the starter and take it in to the local auto parts store where they test them will it determine that prolem, or does the way they test them cut all of that power so i wont know on there machine

they'll test amperage draw on start-up, drive gear engagement and disengagement, and motor function... you can have it tested for sure; but in all reality.. be ready to shell out for a starter bud... and i'd have the batteries tested as well while i was at it and save any headache later on down the road.... contacts are probably about toast since its getting stuck engaged and just continuously drawing

a reman starter with lifetime warranty i ge ton my account for 120 bucks through napa auto parts. so they will be able to tell me for sure or not if thats the problem at the auto parts store? cause id hate to buy one and have it not be the problem and have it be a wiring problem and be out all that money

well i took the starter to the auto parts store and it passed, but i bought a new one regardless, and its still doing the same thing. i complete forgot it only started doing this after we wired a starter relay. so im wondering if maybe the relay isnt closing or something or whats going on

also i know it is for sure an electrical problem because the only way you can kill it is by disconnecting the batteries. i also tested voltage on the big wire to the starter and it is at 13.3 volts. and the little wire only had juice in the crank position so im really confused as to whats going on

well if he's cuttin air off to it in all reality it should die... if the starter solenoid is getting stuck in the engaged position it's going to continue to turn over and removing the starter relay (what controls the starter solenoid) isn't going to do jack.... remove the negative battery cable or something (watch out for sparks as it can cause the battery to explode if hydrogen gas is present) either way; the starter is supposed to have an over-running clutch to protect it for that split second that the starter is still engaged when the engine starts up. this is not a fail safe piece that will spare the starter from dammage in the event the gear stays engaged. if this clutch were to lock up and transfer full engine rpm's thru the ring gear to the starter it will over spin it and quite literally blow the starter apart. either way; starter is toast... the only reason it does it for 3-4 second is the speed of the engine can actually "kick" the starter back
But I agree on teh starter also.

well i had a buddy come over today so he could try cranking it while i did some tests and i figured out the problem. it was something funky with the ignition switch. when the wires are disconnected from the starter everything is ok and wires test correctly on the switch wire. but as soon as the truck starts and the startup lights turn off in the dash, it re-engages the starter switch and continues it to crank. odd scenario ive never seen an ignition switch due that but thats what it was and we replaced the switch and wa-la it worked
