Sullivan Starter and 12V battery

[Cralis]

Is it OK for me to be connecting my Sullivan Hi-Tork starter direct to my 12V (36Ah) battery?

[Leebert]

Yes, It'll love it

[Cralis]

OK, so I won't ruin my starter or destry my engine because off too much power?

[Leebert]

One important thing to remember is that a Hi Torq starter will have no problems starting your Rappy.
If it struggles (and you battery is ok) then you may have flooded the engine. Take the glow-plug out and "start" it for a second or so to clear out the excess fuel then put the glow plug back in and try again.

[Leebert]

PS, my Hi torq runs straight off my 12v battery no problems

[Steve]

The starter is designed to run at 12V, nothing less.

[Cralis]

Thanks.
Does the 36 amp bit not mean anything? I was told that this might be a bit high for a starter...

[Leebert]

The higher the Ah rating - the longer it will go between charges.

[Cralis]

OOO!! Right, I thought it was the amps it puts out... the higher, the more power. Great. OK, learning... slowly guys. Thanks.

Volts and amps are a bit like pressure and flow-rate with water.

Consider a water-tower. The pressure of the water in the pipe at the bottom of the tower is directly linked to the height of the tower only, so the higher the tower, the greater the pressure. That's your Volts.

However, the amount of water that comes out of the pipe at the bottom of the tower is directly linked to the size of the pipe, so the larger the diameter of the pipe, the greater the quantity of water that can come out of it. That's your Amps.

[Cralis]

Ah, so wait.. that means, using the water tower analogy, that the thicker the pipe (the more amps), the more pressure (volts) you will need to get the water to the same high, as a narrow pipe? Or am I reading too much into the example|

[Steve]

No.

The pressure at the bottom of a 10 metre long peice of vertical heli fuel tube (say 2 mm across) is exactly the same as the pressure 10 metres below the surface of the Pacific Ocean (say 5000 miles across). It's the height of water above the measuring point that dictates the pressure, NOT the cross-sectional area.

I couldn' t have put it better, not being funny or anything just my day job is plumbing thats all.
