How to jump start Maverick with dead 12V battery

[JP4AZ]

Ignorant here, no starter?

correct no starter on Hybrid. Your eco boost has a starter.

Just something to look out for when buying a boost pack. Some obviously work but I've read about certain models having issues working properly with hybrid vehicles.

Most likely the ones that don't work are attempting to verify proper connection +to + & - to - and battery is too low or has relay tripped switch to disconnect 12v at a low voltage? If so a jump starter that has a 12v "force on" option should provide current on hybrid and work. If on EB then perhaps jump starter will not have enough amps?

Still ignorant lol. What starts the ICE engine in your hybrid then?

The High Voltage battery in the hybrid. (not the regular 12 volt even though it has one)

This is sounding familiar.

To add to this, MG1.

Disclaimer: I'm assuming the maverick is similar to Toyota hybrids.

one of the electric motors in the trans axle starts the ICE, it runs off the high voltage battery.

MG1 starts the ICE, using the HV battery. To do this, the 12v battery's job is to operate a relay to energize the HV battery. It also powers the electronics, etc. in the truck. The 12v battery does not actually start the ICE.

I know this is very inconvenient, but if everyone would call the provided roadside assistance every time the battery is “dead”, then Ford would have to pay for it to be jumped and what a problem there is and get it resolved. But, as long as everyone takes care of it, it goes unreported and they have no history of how many are really having the problem and nothing get resolved. Just my opinion.

yes, I know, but I don't think the person that asked knows what MG1 is.....that's why I said one of the electric motors in the trans starts the ICE.

There is a video on youtube ., I don't have the link but do a search its up their.

Well, they may not know what the ICE is, either!

It is the safety override procedure for a jump box when trying to jump a vehicle that won't start due to a completely dead 12v battery. Jump box user manuals 'splain how to use the override option. If a jump box didn't work because "Hybrid," the override probably needs to be enabled.

FWIW Mild winter in Texas Hill Country so far this year = U-Pick strawberries are ready for sale in Marble Falls!

I'm in sunny dry Calif.
We don't have ice.
