Start/heat switch&glow plugs

The glow pugs should draw about 5 amps each, so a discharge of 20 would be correct for 4 plugs.

I source switches here http://www.colehersee.com/catalog_top/index.htm
but it takes a little time to plow through the catalog and then find a distributor.

There is some on ebay under buisness and industrial ,antique tractors and caterpillar

Thanks guys, I'll have to do some more checking on the glow plugs themselves once I get the wiring sorted out again. Had planed on pulling leads and seeing if the draw changed any but got to get the harness fixed or replaced first.

OM, found the switch pretty quick that is like the caterpillar but it lists it as being rated for 12 volts. I didn't see another one so I assume that one is going to be out. Definatley looks allot better though then the one that I looked at on ebay. It was made in Turkey

I searched Caterpillar switch on ebay and I only found the one but I'll take a look threw like you said Jason 10/D4

Thanks

Ryan the store on ebay is www.teraparts.com and the item # is 360038580929 Hope this helps. Jason

Thanks for the link. Managed to find it with the item number, for some reason the link just brought up a page with teraparts on it and that was it.

I'll have to send him a email and see if he'll ship to canada or not.

I got thinking about the other one and started to think that it would work. Got looking threw theire website and saw where they confirmed what I suspeceted. You can use it on 24 volt but the amp rating goes to half. Just what I suspected when I was thinking it threw. I sent them a email anywyas to see if they had a distributor close to me. I've heard of them before so I think that there are some around here.

Thanks Ryan

Ryan, get yourself a simple little solinoid and only use the heat terminal on your switch to control it. Switch will last longer that way. Then take the main power on a 10 Ga wire to the heavy lug on the solinoid and put the 10 Ga. purple wire to the glow plugs on the other heavy lug.

Sounds like a good idea bob, thanks for posting. I think we've got some new solinoids kicking around the shop.

I'm planing on redoing all the wiring on the gauges and off the switch to the starter. So I'm going to have to get some wire anyways.

Still not satisfied with that starter that I had rebuilt. I should just go buy a new 50MT and put new cables on and be done with it but I think that'll be next falls project. Once I get the glow plugs fixed it'll start okay threw the summer. I borrowed the neibours battery tester and checked them and they seemed to be okay. Both held up under a load anyways. They were on the edge when it was colder out but still in the green. With a load they droped to about 11 volts. That was at about +5F. Starter still seems to be drawing more power then it should. Sits at about 25 or 26 volts with no load on and drops to 20 or 21 volts when I'm cranking it over. Quite quickly too it drops. I've still got the old solinoid on but it's working okay. Better then those cheap chinese ones I had on there anyways.

Ryan, your starter will draw more than the MT50 because it's working harder.
It's nice to have glowplug draw through the ammeter but if you check the circuit out and it's good wire up the sol direct from the battery and save the ammeter. Meaning power it from the bat side of ammeter not the gen side as is normal to do.
