Portable battery booster - did nothing. Jumpstart attempt by another Miata - did nothing (well, next to nothing). Jumpstart by Discovery, went roaring right away. And on the Disco, no lights flickered, nothing even *noticed* a jump was underway.   Dean Brown (Deanbrown3d) Senior Member Username: Deanbrown3d Post Number: 1368 Registered: 02-2002 Posted on Monday, January 26, 2004 - 11:11 pm:    Same cables?   thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 560 Registered: 11-2002 Posted on Monday, January 26, 2004 - 11:15 pm:    well as good as it feels to have many cylinders at your disposal, the real players here are the alternator ,the driven ratio of its pulley, the current condition of your battery and very important large terminals to clamp to. all that in combination even on a 4 popper will start everthing out there. but still cool to be the big guy to the rescue MM   Chris Browne (Chris_browne) Senior Member Username: Chris_browne Post Number: 595 Registered: 02-2003 Posted on Monday, January 26, 2004 - 11:42 pm:    Jumps work best if you allow the dead battery a few minutes to regain a charge from the good one....in this instance bet a few more minutes of charging time would have worked   Peter J.

It had 2 flatish batteries and it was 10F, (bloody cold). Whilst my Rover was fine there was no way on earth we could get enough wack to start this pig. Gotta say it though...that Ford truck is a total piece of crap...I think my buddy was converted there and then to our cause. He gets only gets 13mpg at best!!!! (Diesel)   D.

(Yes, same cables used on the Miata-Miata and LR-Miata effort.) >but still cool to be the big guy to the rescue< Indeed. :/ Though that effect is somewhat diminished if you're also the owner of the puny vehicle with no battery power, because you left it too long without being driven or properly situated for long-term storage!
