250 rpm
I had a problem with my 98 cranking but without spark. I traced and tested all of the sensors and harnesses until I realized the obvious. The ignition system will not operate unless it sees a minimum of 8 volts while cranking. I hooked up a simple voltmeter and tesed during cranking and had a reading of only 7.65. I confirmed the problem by cleaning the terminals and used a jumperbox. The voltage read an average of 8.75 and it started. I replaced the battery and problem solved.
500 minimum.
According to the owner's manual the battery requirement for the F70 4stroke is: Minimum cold cranking amps (CCA/SAE): 380.0 A Minimum marine cranking amps (MCA/ABYC): 502.0 A Minimum reserve capacity (RC/SAE): 124 minutes I don't know what the reserve capacity figure means.
(i) Reciprocating spark ignition engine 60 to 90 rpm.(ii) Rotary spark ignition engine 150 to 180 rpm. (Hi) Diesel engines with glow plugs 60 to 140 rpm. (iv) Diesel engines without glow plugs 100 to 200 rpm.
I would recommend 500 minimum.
1100-1200 degrees Fahrenheit is the minimum ignition temperature.
Group Size 65 - minimum 650 Cold Cranking Amps (CCA)
burn
It uses a group 34 battery with a minimum of 500 cold cranking amps.
Its least count is 0.001g i.e minimum among other balances.Its precision is maximum due to minimum least count.So electronic balance is an accurate balance.
The minimum temperature the fuel ignites self sustained combustion is known as spontaneous ignition temperature. The temperature at which the substance is preheated and burns smoothly is known as ignition temperature.
Well ignition points is the minimum temperature at which a substance will continue to burn without additional application of external heat. Also called kindling point.
