Good day all!
Here I am going to the brain trust first as my hands warm up by the fire and then to the manual.
D8H 6k hrs, New Cat Batteries in 2022, some new ground wire made in and around the Key’d disconnect I believe it was 4/0, maybe 6 also done when new batteries went in.
Progressive situation : Recent past… The dozer had a slight 1 second delay from the time Id flip the start switch to when the engine would turn over.. this started about 4 months ago during the summer. It had just sat for about 5 month during the winter… however I start it twice a month regardless if I'm using it or not as a Sunday routine.
Usually after first start of the day ( the start that would show signs of the 1 second delay) then the dozer would fire right up like normal.
At this point I was thinking maybe a sticky solenoid/bendix maybe time for a starter rebuild.
Today: Went to fire the machine up.. it had been sitting for a month since I did some ripping with it. I was -1F degree last night. All I heard was a “click” from the starter. First course of action was I put a charger batteries and tested their condition. 1 was at 80% and the other was at 60%. After some charging I got the batteries to 97%.
I also dismantled and cleaned all the connections at the starter. 4 wires run to my starter. 1 ground that eventually grounds on the frame rail next to the tool box. 1 small white wire that goes to a small 1/8 inch machine thread positioned next the the positive. The positive terminal has 2 wires on it… 1 being the large guage power cable and the other is a small red maybe 12 AWG sized wire. I cleaned and tightened all of them. Still just a click from the starter when I tried after accomplishing the above.
Suns going down and Im sitting on the machine thinking what to do next. Then I noticed… as I warm the glow plug using the starter switch I noticed the amp gauge does not show a discharge.. when I go to start the amp gauge does not show a discharge… like it use to. So now im thinking:
1. Bad starter Switch
2. Fuse?
3. Starter needs to be rebuilt
Before I got dark a 1530 here in Maine today I grab my cell phone flash light and start tracing wires/cable… checking for condition/shorts/fuse blocks. I find under the left cockpit platform forward of the where the Batteries sit.. but on the underside a “junction box” and on it says “Electrical Disconnect Plug Inside”. I assume that is just where two cat wire harnesses are joined.
Ladies and Gentleman, can you offer any advice or experience? I definitely could have troubleshot more but I was alone and loosing daylight. If anyone can share any info, system diagrams, parts to replace Id appreciate it. Thank you!!
