When 5hp isn't enough

I have been playing today, i bought a recon alternator on Thursday and today i fitted it to my Bradford 5hp, found an old battery that has been in the back of my work bench for at least two years, checked it with a meter 13.87volts bit high i thought, stuck a headlight bulb across worked fine.

Next i started the old girl up ran for about 30 sec and died, no fuel topped up with some two stroke fuel i have, cranked it up again, great, connected the wires and it virtuly stalled the engine, so noww i need

More power

I could only get a 70 amp alternater i wanted a 100 amp+, good job i didn't, may have to rethink the inverter setup

Stu
I heard somewhere i think (don't quote me) that an alternater kicking out 100 amps uses 5bhp to turn it,

I will take a pic tomorrow and possibly a video, i think i have a flat battery somewhere just to see how much it barks

Stu, it would be fine, if you were running say two 55w 12 volt halogens that equals 110watts divided by 12 volts is just under 10amps, not a problem, but i wanted to run a 2000w inverter and at full load would take about 300 amp from the batteries so i think i am going to have to re think my electric grill and go down the bbq route.

I can get you some 6v 100amp batteries @ £5 each but no guarantees with them

Thanks Stu, thanks, but i have some batteries already, i was called out on a breakdown early this year on a big charter yacht, they had starting problems, told to pick up two new batteries and fit them, so i did, still wouln't start, checked the systems, found a fuse blown, i have still got the batteries 2 x 170 amp still not two years old, yacht was less than a year old
