Electical dead

[eeshed]

Dear community,
My FJ1100 is electircaly dead, no headlights, no start, no signals. Where do I start troubleshooting?
I did work on the electrical with replacing the turn signals with LED+resistors. Also I attempted to put the coils on a relay. The relay was draining the battery and I removed it, plunging all back original.
Thank you for any suggestion,
Eyal

Are you sure it is back the way it was? Having an electrical problem right after working on the elec-trickey stuff means something was missed.

  Go back to basics mate...

ALL connections are clean and connected??

Battery is fully charged and connections are on tight??

No blown fuses apparent??

Make sure that the battery has a charge then check the main fuse.

Eyal,

Remove everything that you have added lately, and put it all back to the stock configurations.  LEDs can cause problems, and there are no standards for what you may find on the market.

A lot of stuff goes though the flasher unit, which you may not expect.  You should have a spare flasher unit anyway, so try a good one, before you get too wrapped around the axle here.  FleaBay may have a used one for you, but good luck with that.

Cheers,
Red

What he said.

The relay install is probably where you went off the rails, though.  The coil side of the relay should have been fed switched power.

Make sure your battery is fully charged before you start looking.

It looks like I have multiple issues. First, I discovered that I blew my 30A fuse. Not knowing that there is a fuse under the seat, besides the battery, was my first point of failure. I replaced the fuse, and now there is head-light, and turn lights. However, the starter doesn't work.

The red/white wire at the relay gets 0.22V (instead of 12v). I traced the blue/white wire to the starter relay, and it also gets only 0.22v.
Where do I look for the connection failure?

If I can trace where I lose the 12V to the main relay I believe the problem will be solved.

Thanks,

Get yourself one of these. They have a surgically sharp point. You can test for power through the insulation, poke it into connectors without pulling apart and draw copious amounts of blood if you hold the wire between you fingers while trying to press it through the insulation.

If you use one often enough and get familiar with the brightness of the globe you can even approximate voltage.

These testers will find 99% of electrical troubles. I rarely need to use a multi meter.

I also carry one in and on all my vehicles.
