<DIV>jeff…. regular led acid battery ?? <FONT color=#ff0000>Everstart Maxx27 800 CCA regular Walmart battery</FONT></DIV>
<DIV> </DIV>
<DIV>When it died, did any of the electrical items still work? Lights, etc.? <FONT color=#ff0000>when it first occurred ,, when I tried to restart, .. starter just clicked and I remember the a/c fan still blowing</FONT></DIV>
<DIV><FONT color=#ff0000></FONT> </DIV>
<DIV><FONT color=#ff0000></FONT> </DIV>
<DIV><FONT color=#000000>Donald... How large is the cable from the alternator to the battery? </FONT><FONT color=#ff0000>feed from battery to alternator is #4 wire<BR clear=none></FONT></DIV>
<DIV><FONT color=#ff0000></FONT> </DIV>
<DIV><FONT color=#ff0000><FONT color=#000000>Dave... I was thinking a dirty battery clamp.</FONT> battery clamps are new this year and clean, no corrosion on connections</FONT></DIV>
<DIV> </DIV>
<DIV><FONT color=#ff0000><FONT color=#000000>John... How is the volt meter in your truck grounded, to the frame or to the motor?</FONT> voltmeter in dash is grounded to dash frame voltmeter used to check under hood is grounded to frame not engine. I'll go back and check ground connections. Alternator has a ground terminal of it's own... it's #10 wire grounded to the frame and of course the alternator is grounded through it's mount.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT color=#000000>Pat... what is the relationship between the frame terminal & the rest of the electrical system? </FONT>Terminal on the frame rail is fed by a 4' piece of #4 wire from the i/p solenoid lug where the cable from the battery is connected to the solenoid.</DIV>
<DIV> </DIV>
<DIV><FONT color=#000000>Jimmie.. What's the voltage at the terminal with those accessories 'on' but the engine 'off'</FONT> hmmm ?? don't remember checking that, … I'll do that</DIV>
<DIV> <FONT color=#000000>How big is the alternator?</FONT> 100 amp single wire from CVF racing</DIV>
<DIV> </DIV>
<DIV><FONT color=#000000>ya'll have given me lots to check and recheck and some I haven't thought of... going back through my diagnostics and check connections too. I bought a 500 amp load tester yesterday and will put sufficient load on the battery. Battery is under the cab and I have to lower it to check it out and with the low truck, I have to raise truck on jackstands.. silly me, I thought battery would be a low maintenance item ...duh. so checking at a shop somewhere is a very large pain.</FONT></DIV>
<DIV><FONT color=#000000></FONT> </DIV>
<DIV><FONT color=#000000>points I'm considering.... larger ground wires from frame to engine.... alternator to frame and check resistance from solenoid lug to the terminal on the frame... the saga continues</FONT></DIV>
<DIV><FONT color=#000000></FONT> </DIV>
<DIV><FONT color=#000000>thanks for all the replies and points to check.. you guys are the best</FONT></DIV>
