I am needing to remove a fuel solenoid from my motorcycle.
I know I need a 39 ohm resistor for this, but am not sure what wattage I should use.
This will be from battery to ground.
Battery is 12 volt 10 amp.
How much current does the solenoid take ?
“This will be from battery to ground.“
W = 12V 2 / 39 = 144 / 39 = 3.7 watts being used.
Rule of thumb 2 to 3 this value.
A 10 watt resistor should run warm not hot.
I have no idea.
I don't want to cut into them Incase I need to use them.
So I don't know the coils to figure it out.
I've been trying to find online, but no luck.
Is there any way to find out using an ohm meter?
The leads aren't strong enough, they will just bend. Also the resistor casing might crack under the strain. I suggest using a screwdriver or a ratchet set that fits the screws or bolts.

Why? What is the resistor supposed to do?
That's what I was wondering. What does "I am needing to remove a fuel solenoid from my motorcycle" mean?
