Jumping ohms

[spitzer26]

So i got a single coil build right now reading at .70 but i always notice its jumps down to .69 sometimes to .71 is that normal ? Thanks

Ohms change as temperature changes. Perfectly normal.

coils can change resistance + or - by 0.2 ohms.

More drastic changes in resistance might be due to other factors, such as a loose post screw on your rba, the wire touching something it shouldn't and grounding out, etc.

I've experienced a drop in resistance of 0.5 ohms from a loose post screw. Luckily I never build lower than 0.6 ohms, because 0.0 ohms is a dead short. That can make a battery go into thermal runaway.

You already posted the same question elsewhere.

To your question

That resistance change is absolutely fine

If it were .7 to 1.2 there would be issues but your changes are typically fine

Try tightening your leads.

No problem on that.

quite normal... especially since the accuracy of the ohm meter in most VV/VW units is +/- .2 ohms anyway
