Newbie Help Please

Here's link to the VS wiring diagram.  Check fuses and grounds first.

I’m with Wolfgang on the need to check the grounds.  A funky ground can make your directional flasher work really fast.

The common denominator of brake/tail/license plate lights is a common ground that has probably loosened and fallen off.  Pick a light, find its’ ground lead and follow that to the frame/chassis ground to make sure it is tight.  If it is, clean it anyway and use an ohmeter to see if it shows a short between that ground point and a known chassis ground.  There is supposed to be a ground strap from a stud at the front of the transaxle over to the car frame.  Make sure it is there, the contacts are clean and tight.

DO that and report back on progress.  We’ll all help you fix this.

My bet is that it is a ground issue.  Make sure all lights are grounded to the frame or have a ground wire that returns to the battery.   For added insurance I would add a ground wire to each fixture (under a mounting screw) to the frame.  Remember these are fiberglass bodies, therefore a sufficient ground is required to each light fixture.  

Thanks Everyone!

I will dig into it in the morning a let you know how I make out.  I really appreciate the support!

Dash indicator stays lit and signal flasher is fast = ground issue....it will take a bit of time to confirm all light, flasher, steering box, main ground etc. . In one case it was a bad filament in a bulb bulb.

i belive  there is supposed to be a ground to frame wire by the passenger rearwheel?

Yup there should be a mesh ground strap at nose of trans and another from battery neg post.  It does not hurt to add additional ones.  Just make sure the mounting surface is clean and bolts are tight.

Okay, I went through every ground I could find on the car this morning.   I could not see or get to the transmission ground.  Not sure if  there is one.   Turn signals are now working great.   Headlights work.   But still no brake lights, parking lights or license plate lights working.   Cleaned all the bulb sockets and checked all bulbs.  Changed the fuses and checked all connections.   Any other thoughts on what I might be missing.  Could a bad brake switch do all that?   Thanks again!!  

Brake light switch would only affect brake light - not license plate or parking lights.  Put a jumper wire from the central ground in the back or even one of the parking light grounds (probably a brown/black wire) to a clean ground on the engine.  That would show if it was a bad ground.  Get a volt meter and check the hot wire to a parking light with the jumper ground still connected and parking lights on.  If no voltage then its wire from accessory (switch with key - switches do go bad or wires come off it under dash) or hot feed to fuse. 

And by clean, all contacts pos/neg need to be shiny metal to metal with no paint in between. 

fuse?

I had a thing once in Bridget where the fuse blew and I couldn't tell by looking. Rare but worth a check. In that car the brake lights/tail lights and license plate light were all on the same circuit, along with the instrument lights so you'd notice.
