Flat battery

8 amps are not a lot. I would leave it to charge for a while.

My starter motor is rated to draw 160 amps and a reasonable battery will put out around 600 amps when starting, so 8 amps is a drop in the bucket.

This is why the Poms always have a cup of tea in a crisis. It gives you something to do while you wait. :-)

I would have to say no also, all the electronics (SCRs/Diodes and even the zener dioes) would not handle the current even if it is for a short time period.

Do not - under any circumstances attempt to start the vehicle like this. At the very least you will burn out the leads, worst case you will destroy the charger, depending on fusing.
As stated above, charge the battery with the Honda, have a cuppa or more likely lunch & visit friends too cos it will take probably a few hours charging at this rate to get sufficient charge into the battery. Disconnect the leads before trying to start.

Life's too short to say .. "I can't do that !"

OK guys..

I've DONE this. Well, I've Disconnected my truck starting battery and connected it to the Honda 13V circuit. I left it for 20 minutes and the truck started satisfactorily. Don't do this if the battery is sus, or reading below 9V, the generator blows fuses then!

Hi all, I've done this too, using a Honda EM1000F 4-stroke generator. I stuck it on charge for about 20 mins and then tried to start, no go. Put it back on for another 20 mins to half hour and tried with the genny still connected and running, and it started. Don't seem to have damaged the genny, but from what Neil & Lynne say above maybe I was really dumb??? BTW, vehicle was a 4Runner 2.8 litre diesel.

Our outback battery chargers can jump start a large 6cyl diesel in about 1 minute, or can fully recharge the cranking battery in about 1 hour.
Quite handy if your alternator claps out in a remote area, - or if your winching out of a big bog and stall the engine.
This happened to a customer of ours in the middle of the jardine river recently (he was not supposed to be there), he lost the brand new patrol, he later invested in one of our chargers which would have saved him..
