What happens if you pull a fuse while car is running?
While the car is running, the alternator (hopefully) is charging the battery, so a current draw should not be too big of a problem in most cases. However, you should try to fix the current draw as soon as possible, I do not reccomend pulling the fuse when parked as a long term solution. Use this only in a pinch.
What happens if you pull out a fuse?
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. The result is that all lights, outlets, and appliances powered by the circuit will go dead suddenly.
Will blown fuse keep car starting?
A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.
Can you pull car fuses out?
If you can’t just yank a fuse out, you need a plug puller. If you’re lucky, your automaker has provided one right in the fuse box. If not, try a pair of tweezers. If you encounter tubular glass fuses, look for one that’s black inside or no longer has its filaments intact.

Can a 1985 GM Truck Pull a fuse?
I don’t know how your 1985 truck is set up but in my late model GM car I could pull all the fuses and relays and it would not isolate 2 known areas of current draw, namely the seat motor for seat adjustment and the power windows.
Can a seat motor cause a fuse pull?
In my vehicle these are covered by dedicated circuit breaker fittings not by the usual standard block of fuses and relays. I am aware of possible current draws occurring with faults from either of these items (ie. a faulty seat motor and a power window motor that continues to run due to a faulty switch).
When to disconnect battery for Fuse pull test?
I did find a TSB that says that the computer might cause a draw only after it has been turned on and then off, so disconnecting the battery to set up the test gets rid of the draw if it’s that.
