I have had a small issue for quite awhile now and I have been troubleshooting and searching out answers with the help of this forum to try and resolve it. I have not seen an issue quite like the one I seem to be having so I figure to finally post in hopes someone may be able to help.
Here's the done that list:
2 load tested verified fully charged batteries (swapped out twice with different batteries issue still remains)
4 tested good rebuilt alts (swapping these in any combination did not resolve issue)
I have cleaned ,checked, tested all fusible links, grounds, instrument cluster wiring and anything else I could stick a meter into. I have replaced all relays and solenoids done doghead mod. I have installed a manual push button for glow plugs. I have all gen lights acting as they should when you turn key on.
Everything sounds like it should be working correctly right? well to a point that is correct. the problem is I lose voltage when its warm, if the temp outside is above 60 degrees or the truck has run for awhile and warmed up to operating temp. my 24 volt gauge and my 12 volt gauge both sit as they should when its cold (at the white tick on the green and at the 14 volt mark ) when it is warm it drops both gauges down some and that gets worse when adding heater lights wipers etc. and it does not recover unless I turn items off . it drops to almost the yellow on one and almost to 12 volts on the other.
Any ideas on what I might have missed in my trouble shooting that could cause this issue?
