No Start?

[jeepboy_90]

I have experienced a no start condition with my C303. 

 

Today I tried starting the vehicle with the choke on. Dash lights came on and starter engaged. I stopped to adjust the choke and nothing. No dash lights, no start, nothing. 

 

Are there any standard issues like this? 

 

I have no dash lights, dome light, nothing. Batteries are at proper voltage, power to ignition is at same voltage. Tried jumping main to accessory, nothing. 

 

Amps? 

 

Help, thank you...

Bad condition of battery/ "ground" connection?

 

 

Might get ok voltage at no load, but voltage drops when you engage starter.

It sounds as if your ignition switch might be broken! This may be due to wear but can also be caused by poor contact in the starter solenoid. Poor contact in the solenoid causes most of the current to the starter to go through the ignition switch causing the latter to fuse together. Before you try to hotwire, try running just the starter. Make a cable with a 30 - 40A fuse and connect to the solenoid control connection. Connect the other end of the cable to the battery. If the starter works without the fuse blowing the starter motor is probable OK. If the fuse blows, the starter must be addressed.

Check the ignition switch by hotwireing. If needed, replace the ignition switch.

Thank you for the info, I will be heading over to the vehicle this morning.

Ok, Success !!!

 

Trying the above, was still not getting anything from the batteries. So I figured even though they were showing 24v+, it had to be the ground. I took all the grounds off, cleaned and re-connected. 

 

Started like a champ, like normal.

 

NOW - I have no headlights, brake lights, turn signal dash lights? Do these share a common ground that could have come loose when messing with the ignition switch? I looked at the wiring digram, looks like maybe the dash itself is grounded? Fuses are all good.

 

Thanks...

all the features you mention have different feeds, so it's probably a bad connection somewhere in ground connection..

[SBAT111]

Aah, JDW was spot on concerning you first question

The new phenomenon seems more like a problem related to the positive feed since most of the lights have "local" ground connections.

The fusebox itself is a bad thing,the rivets that connect thru the bakelite baseplate come loose and causes trouble.
Check it......

Sorry for bad spelling.....

This could also be caused by a loose wire on the "mörkläggningsomkopplare". The switch that turns the lights from off, normal or low light mode.

 

Those wires are short and when you move the dashboard around they can jump off.

 

I had the same problem, when I had the dash loose a wire jumped off and killed all lights and vipers. The engine still started and run fine.

 

Remove the padded "knepad" and you can reach it without moving the dashboard.

UPDATE: I was able to find a set of wires that had pulled off the back of the "blackout" switch. I now have headlights, wipers, dash lights. But not turn signals or high beams. Moving the dash around I can get the turn signal indicators to light up(sometimes), but trying to active the switch does not activate the relay/flasher. 

 

Before going wire by wire, is there any input? Everything worked yesterday before puling the dash.

 

On the back of the "blackout" switch, there is one open terminal, is the correct?

 

Thanks again for all the help.

You could check the connector which is on the right side of the dashbord.

(Don't remember if you have to loosen the panel for heating etc.)

The other part of the connector you will find below the dashboard. (see picture)

Peeter is right, losen the choke/heating-panel and a white plastic connector appears, most cables from the fuses passes through this one, and this one also likely to jump off when the dash is moved around. If it has a bad connection the indicators stops working first, at least thats what happened to me.

Thanks for all the help. 

 

We are back in business, ended up tracking it to the flasher relay. Popped the cover off and found some bad corrosion, cleaned it up and success. 

 

Yeah!

I believe that further assistance from us requires some photo's of the object.....
