jump start a diesel?

[roscoFJ73]

Where would you introduce the ether?

As close as possible to the combustion chamber. Where ever it is practical to spray in. BUT NOT PURE ETHER. Use the compound types that are about 30% ether. It doesnt work so well for flat batteries. If you have fuel, the battery should compress it and ignite it. Ether based sprays are more for getting an engine running long enough to heat up the combustion chamber and suck the fuel through when you have a good battery. But it can still work.

Wait...ether? When and why would I have to use that?

Cruiserpilot asked about it after Lowenbrau mentioned it. Read my post, it answered both your questions.

Push starting seems like it wouldn't work because of the high compression
ratio unless you had a *really* steep hill

Push started diesels a few times.

Get it rolling good, and pop the clutch in 3rd or 4th gear.

Disregard. Got ‘er started. Thanks, all!

I've roll started my BJ73 quite a few times, you've got to hold the accelerator down otherwise it just spins over like the ignition is off.

At work my GF was often having to push start the HZJ75. They've only got a small ramp out of the shed but with about the pace of a slow jog it fires up in reverse on gravel.

I've got a couple of the little lithium jump starter packs and they work great, I use them often on the farm and have started diesels from dead flat a number of times. I've been through a couple of sets of the leads though, I made my own that don't have the stupid relay in them. Once I got rid of that the packs performed much better.

This is what I have now. Lots of starting power, sure takes the sweat out of being alone in camp.

Dare-what do you mean by relays? These ones here in the US have the only requirement that they be disconnected within 30 seconds or the truck alternator back charging will bugger up the jumpstart battery. But no relays on the connectors. It couldn’t be easier to use

There's a thingo built into the leads that only gives power for a short time or often in my experience, not at all. It really doesn't get along with diesels as it sees the current from glowing and then cuts power after a couple of seconds. I guess it's to stop back charging and accidental shorts. I cut the bastard thing out and soldered the wires direct to the plug, before that it was simply impossible to jump start my 2L powered 4runner which needs to glow for 20-30 seconds.

I've got one of these. It was bought from Repco and branded SJS so I don't know if it's all the same inside.

And one of these. I prefer this Suaoki, it seems to have a few more beans and is just a more polished product. It's battery certainly seems to last longer too.

Both are very capable though, they've each started IDI diesels and an LS1 from absolutely dead flat.

After I melted some clamps I bought a set of these. There's just a bank of diodes in the box. They've done really well but recently the solder on the diodes failed so I've got to unsolder the diodes and use a bit ballsier solder. These leads are a bit short which is annoying but it's hard to complain given the price!

Good thing is now we can all have a solid back up for less than the price of a series 31 battery and they keep for 6 months plus under the seat without a bother. That one, 800 Amps! Impressive. Mine will start all the big NAmerican diesels though, as well as my relatively smaller 12HT of course
