j hancock Posted March 15, 2017 Share Posted March 15, 2017 Appears your series parallel switch is gone also so start fresh with a 12 volt starter, new cables and two 12 volt batteries. Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
rwood64083 Posted March 17, 2017 Author Share Posted March 17, 2017 Thanks Jim. I'm just trying to put together ideas on how to start the truck. Make sure it runs and moves before dumping a bunch of cash into it. First research on a 12V starter is looking like give or take $300. As reading in another thread it was suggested priming the fuel system and pull starting in 3rd gear. I have two fully charged 12V deep cycle batteries. Maybe wire them up and give it a pull, see if she fires. Questions on converting 6V to 12V: Is this not a positive ground system? Aside from changing the starter won't I need to do something with the generator and regulator? Is changing the polarity of the Ammeter the only gauge I need to worry about?

fxfymn Posted March 17, 2017 Share Posted March 17, 2017 That is a 12 volt system already. The original system used a series/parallel switch to supply 24 volts to the starter, while all of the accessories used 12 volts. It is a positive ground.

j hancock Posted March 17, 2017 Share Posted March 17, 2017 For test purposes, if the original starter is there, do some redneck wiring with some good heavy jumper cables making your two 12 volts into a temporary 24 volt and see if it turns. Be careful! Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...

Be careful! Good idea. Come think think of it, I bet I could rig a single 12V battery to supply running power. Then take the two 12V deep cycle batteries, connect in series and give that a shot at the starter. Thanks, you got my wheels turning. 2 hours ago, fxfymn said: That is a 12 volt system already.

For the life of me I don't know why I typed that saying 6V. I knew it was 12V with 24V supplied to the starter via the series parallel switch. I work with a lot of old farm tractors that still run 6V positive ground systems. Gotta remember to keep all these things separated in my head 1 Quote Link to comment Share on other sites More sharing options...

On the diesels all you need is to turn them over. The rest is mechanical. I've been playing with my truck and all I have is the batteries going to the starter. Then I use a jumper wire to activate the solenoid. 1 Quote Link to comment Share on other sites More sharing options...
Maddog13407 Posted March 17, 2017 Share Posted March 17, 2017 (edited) why use a battery at all? any diesel will pop start in 3rd high. rig up a can with fresh diesel, two lines, prime up the fuel system , try to pull start it ,if shes a good runner, invest in a starter and some new cables. if shes skipping, we have a cure for that to Edited March 17, 2017 by Maddog13407 2 Quote Link to comment Share on other sites More sharing options...
Phase 1 Posted March 19, 2017 Share Posted March 19, 2017 (edited) Check the starter before you buy one. If the series/parallel switch is gone it may have already been changed to 12V start. Edited March 19, 2017 by Phase 1 Quote Link to comment Share on other sites More sharing options...

Given the previous Antique Tractor Salvage Yard owners I'd say there's a good possibility there have been things disturbingly rigged up and/or removed and sold. I'll get it sorted. Appreciate all the input. Certainly helps me put ideas together. Quote Link to comment Share on other sites More sharing options...
