As per a previous thread i decided to use the shut off solenoid as a switchable live feed, i planned to use it to trip a relay to a high current line to my battery.

I thought i'd test whether it was ign live feed with a wire and a lightbulb. As i couldnt get a good connection on the solenoid itself i unplugged the feed to it and plugged my little tester lamp direct into the +ve feed to the solenoid. Turned on the IGN and earthed out the light bulb.

The light bulb didnt light, i just heard a click

Now the car wont start with it all connected up again
 
Fuse 3 blown in the control module. PHEW!!

But on the same note... this wire is supposed to be possible to use as an ignition live feed? So where can i earth it to through a relay?
 
erm.....
if yu have blown a 10A fuse by connecting a lightbulb in a power line - that means yu musta used a 120Watt bulb!! :eek: - or yu shorted the live to ground by mistake.

Summat aint right here :confused:
 
your are probably right. Although i doubt it... i got a thin ass wire connected to 5w bulb on the side... i plugged wire into solenoid live feed. tried earthing on a few body locations, got nothing. earthed on battery -ve and it blew.. i dont get it.. the buld should have lit a little bit at the very least. I will try again with a relay. see if i can make it click
 
no!
dont use a relay.
A 5W bulb is fine - it will only take less than .5 of an Amp and should not blow a 10A fuse. recheck what you are doing. If in doubt use a multimeter.

Er is this the prob Daft ???
 
Nope
If one side of the light bulb was in the live feed wire and the OTHER SIDE of the bulb was earthed - that is correct.....
the bulb would limit the current flow to .4166666 Amps

Yup see yer point but I'm imagining a scenario where the wires are frayed and stuck into solenoid connector, and being held by hand (i.e shorted) and connected to earth. Is that a possibility MrPdude? :confused:
 
Ok i guess i must have cocked up somewhere.... taking extra care what i doing... bulb lights. fuse remains..

tfft!

thanks for quick responses ppl :D

I had abut 1.5mm of unsheathed wire protruding from bottom of bulb. as i have pushed the base of bulb to earth, i can only guess that this 1.5mm touched earth first... hence no light and blown fuse.


Although i may add... tinned nice smooth wire... im not the most professional person you will meet, but im not a cowboy/retard ;)

Sorry didn't mean to suggest you were a retard, but when doing things like that it is very easy to slip n cock it up, test wires are fine, it is of course still possible to short things out using a multimeter. ;)
