Darkroom processing with light on

Hi all

I am wondering if someone has ever tried to fix negatives with the
lights _on_ (I mean, switch the lights on immediately after the acidic
stop bath) ?
From what I know about film chemistery nothing should happen but...
So has somebody conducted some fiable, sensitometric tests ?
Please note that I am referring here to an acidic stop bath (2% acetic
acid, pH about 4.5) that should arrest the activity the developer
remaining in the emulsion. But can the higher pH of a "neutral" fixer
let the developer acting again ?
Thanks for any comment,

I have a john deere 2010. with a generator it is a pos ground when I got it someone put a alternator on it dose this change the ground to a negative

To be sure you can use a test light, touch one lead from the test light to the frame of the tractor and the other lead to the Positive + terminal of the battery if it lights up it is negative ground if not touch the negative - terminal of the battery and if it lights it is positive ground.
One thing to check if it was converted to negative ground is that the switched the wire on the ignition coil.

john-deere-2010-generator-pos-ground-qumruwi2utlvsp5qakcuppif-5-0.jpg Using your test light you need to turn the key to run position, touch one lead to the negative - terminal of the battery and on the ignition coil touch the Bat + threaded stud it should light and means it correct and do nothing. if not touch the Dist - threaded stud and see if it lights if it does move the wires on the ignition coil to where every wire on the Bat + threaded stud is moved to the dist - and every wire on the Dist - threaded stud is moved to the Bat +.
There is a good chance your charge gauge is backwards also , it swings in the direction the current runs and when it was reversed so did the needle on the gauge and in the case it does not mean it is discharging.

Sony55"KDL55EZ711,I POWER ON and only red (led)turns green. I don't get picture nor sound.Tried flashlight test. Negative. Looked in back for,lighting in darkroom and nothing either.witch board is bad

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Can I scan a negative 4X5 black\white to make a photo

In general, yes, you can scan a negative and make a photo from it. I don't really know your model scanner, my Canon 8400f has a film adapter and a light in the cover, but would have to scan a 4x5 in sections and I would have to piece it together after scanning.
The results I get from scanning negs are very good, as good as I ever got in my darkroom.

What is an enlarger?

As an engine is the heart of a car, so is an enlarger the heart of a darkroom. It is the instrument through which negatives are brought to life. Along with a good lens, it is the enlarger that the rest of the darkroom is built around. A darkroom can have the best plumbing, a great stereo and stainless steel trays, but without a good enlarger and lens, it can be hard to produce quality images.

I need an ignition switch wiring diagram

Hi, Nameisonlytwoltrs what a strange name, by the way, nice novella. The solution to this is simple, most ignition switches for motorcycles/scooters have identifying letters stamped near their connection terminals, B/BAT/+ for power input, I/IGN for the ignition circuit, L/LT for the light circuit, A/ACC for the accessories circuit. Now if your switch has no markings you going to need a 12-volt battery, a test light, and a jumper wire with alligator clips. If your switch has 4 terminals there will be 16 different possible combinations for the process of elimination. Connect your jumper wire to the battery positive terminal and connect/hold the other end to any terminal on the switch. With your test light connected to the battery negative terminal start probing the remaining terminals with the ignition key switched to the on position and observe when the test light illuminates completing the circuit. Move the jumper wire to a different terminal and repeat the process. Keep doing this until you find the right combination that makes everything work.
Good luck and have a wonderful day.

My chevy cavalier back lights wont come on i put new sockets and bulbs...what seems to be the problem and how do i fix the problem myself

Either the back-up switch is bad or needs adjusting. It's pretty much when you put your car in reverse, it makes a switch which makes your back-up lights come on. Not sure about yours, but some are located under the gear shift console when the gear shift is moved it will then make the switch, and some are on the transmission. I would try adjusting the switch first, which the car will have to be in reverse to get the lights to come on. It can be a little dangerous, but make sure the car it secured and someone is helping you. Gear shift in reverse, with someone holding the brakes while the switch is adjusted. It hard to explain this process, but wish you luck in fixing it.

Battery drains down over night,new battery alternator is charging

That means that there is a short or a problem to the wirings to car stereo, or doors. No matter if the radio is not mounted.

Inspect all the wirings to car stereo , doors and internal lights.

If you do not find anything you will need to check amps to door, internal lights car stereo, etc, by doing a draw test on this wirings.

This will tell you where the problem is.
