Chevrolet s10 4.3

I think Wayne may have put his newspaper in one of the ammo-box char-containers, a little further away from the intense heat :smile:
At least your newspaper didn’t turn to white ash. Probably no leak.
I’ve noticed the rails feel warmer going slow even though the thermometer shows moderate gas temp. The wind drag cools the tubing surface a lot. Just saying.

Jan, any progress on the inspection issues?

No, I have not tried yet.
Where and bought nozzle cleaning today, and thought to put in a new gasoline filter first.

JO, do you usually drive on petrol for a while before the inspection?

Only on my way there and only because they won’t let me in with a hot gasifier.
The Mazda is a -91, has no oxygene sensor and only a simple idle-CO-test is required. I think 3% is allowed. I just tell them everything is manual control on a woodgas vehicle and I turn the fuel pump pwm down to any number they like to see.

Yes, putting pwm on the pump would work.
But I wonder if my system works with lower pressure or flow, seems like it is sensitive to low pressure.
Shouldn’t it affect the fog during the injection as well?

My car drains the battery if it stands still for 3 days. I have tried to remove fuse by fuse, but it still draws power, does anyone have an idea how to find the fault?

I take it you’re talking about spray pattern and yes it will probably be somewhat affected. Still good enough to run a really lean idle though.

About the battery draing, I would install a battery main switch and let the cause of problem show up when I least expect it.

You’re a funny one, but I mounted in a switch yesterday, so we think a little similar. :grinning:

I always put a test light between the positive post and the positive cable and then disconnect stuff one by one till the light goes out.

I had the ampermeter between the pole and the cord, and then took out the fuse, but it pulled power even though all the fuses are gone.
Was that what so you meant?

Building on what DonM said:
Some circuits on American Vehicles are unfused.
These use fuse link wire for protection.
One of these is the alternator. A possible culprit.
At the starter mounted solenoid is the big cable from the battery positive. For decades GM used this terminal stud as the mounting point for the main accessory feed wires. Later GM’s these were moved to the battery positive terminal.
Regardless. You would need to remove these main accessory feed wires one at a time monitoring the test light or meter, to see which branch had the draw.
Then work outwards.

Or sometimes it is the actual battery internally degraded self-discharging.
Our 2007 Hyundai is doing this now.
With your new master disconnect switch - still a problem? Yes? It is the battery internally.

Ok, yes I’m a little wondering, I can have windshield wipers on even though the ignition is off, I have tested a new battery, I will try to remove the cables on the + pole, Thanks Steve.

Windshield wipers able to work with the ignition switch OFF is bad.
Hope it is only a bad/worn ignition electrical switch leaving the Accessory contacts connected.
Or a master relay internally sticking ON in the PDC.
Hope/pray it is not an under the hood Power Distribution Center electrical short circuiting. Insect bugs/nests. Plastic melted, then conductors touching. Flooded water corrosion damaged.
Last resort demount this and inspect the undersides.

Opps. I missed one cause of windshield wipers staying on with the ignition switch OFF.

Internal wiper motor assembly fault.
We do not actually turn off our windshield wipers. We enable a wiper assembly internal turn-off circuit. Once the wiper arms are in the proper parked position then an internal switch is opened up stopping the wiper motor.
Bad switch or mechanical mechanism fault will cause this.
Actually hard to diagnose.
Have to have an electrical pin plug diagram. Check for continuity park circuit to ground on-off, on-off with rotation.

The possible problems I stated previously should cause more faults than just the wipers.

My buddy’s 89 Cherokee had that exact problem. His turn signal/wiper/cruise control lever was snapped and randomly set off the wiper until I replaced it. He had kept complaining about the battery going dead if you didn’t drive it every day so I bet those were one in the same issues.

Was it the wiper motor itself that was the fault?

In my friends case it was his lever being broken and leaving the switch on partially.

Inspected today, just went through, think the car is running a bit uneven, wondering what it could be.

Congratulations!
Those emission tests are a lottery. It’s a pitty the tickets are so expensive.
