Well said....
Well said mh rogers............your right on. I could add, that when you talk about the "Doos" not liking weak power, your very right. If the power output of the battery falls below so many amps, it will not even try to start. The amps needed are different according to the engine size and whether it's a "smart" electronic engine (4-TEC) or just a simple 717 or 787.
But crossing your terminal post, will do a MPEM in, in an instant. The 5 amp fuse is there to protect the MPEM, but in some circumstances, before that fuse "pops", it's sent the charge through that did the damage.
So, great input and well said mh........I agree totally.
