2010 Royal Enfield Bullet 500 - 1982 Honda CB125s
[SOLVED!!!] Issue was caused by bad ground where the dashboard lights insert into the dashboard seen here : http://imgur.com/a/DgcfE just needed to push those bulbs in further and now everything works. Went for a fun ride
Hi everyone,
Thanks in advance for any and all assistance and for reading

Important info: Recently I have upgraded my 6v to a 12v system and followed steps detailed on this forum from other CB125s users. Components changed/swaped : added 12v relay flasher, 12v headlight, removed 6v R/R and replaced it with a Sparck Moto 12v R/R single phase as recommended by a representative who posts here. Also changed the 6v cell battery for a Bike Master tru-gel 12v 4a battery. This is it here : http://www.dimecitycycles.com/vintage-cafe-racer-caferacer-bobber-brat-chopper-custom-custom-motorcycle-electronics-parts-small-12v-sealed-trugel-battery-78-0531.html
Since the bike is 36 years old the wiring is a little ratty so I bought new brass connectors and replaced a good amount of them. I also put in a 20amp fuse. I should be using a 15amp one but they are hard to find and I can only buy an 8 dollar pack that has a single one. Decided to buy the 20 amp pack of 6 for 3 bucks.
All the electronics on the bike now work and I am super happy except for the front right turning signal. It WAS working, then I went for a ride and it suddenly stopped working.
Steps I've taken to diagnose the problem:
- Removed the bulb and put it into a different turn signal. Bulb worked so it's not broken.
- Used a multi meter to check continuity on the single wire for the turning signal. Continuity check determined the wire was in working condition.
- Replaced the brass connectors for the male tip of the turning signal wire and replaced the 3-way female connector for the right turning signal from the main wiring.
- Changed the order of the connectors on the 12v flash relay. No change. So went back to how it was.
Oddity that I noticed : when I use the left turn signal both signals front and back work. When I switch it to right side, front right turn signal does not illuminate but the rear one does but the brake light also flashes. I don't remember the brake light flashing with the signals and it doesn't when it is set to left. I tried unplugging the rear brake light to see if it was screwing with the front turn signal but it just stopped working and made the rear turn signal stop too.
I am just looking for what might have caused such a strange issue? I luckily found a shop in my town that does electronic repair so I just want to know what could be causing this so I have more information when I bring it to the owner to try and fix.
I was thinking maybe it is the ground but I disassembled the turn signal and it would appear that it simply grounds by the metal rod that extends it from the bike touching the headlight bracket. It is indeed touching and tightly screwed in.
Thanks
EDIT
I'm desperate to fix this so I can go out and ride and have posted on a few forums. I was recommended to attempt this procedure and will do so and report back :
To test this (earth connection):
-Make sure the neg terminal is disconnected.
-Remove the diffuser (orange plastic bit) and bulb
-Screw housing back into the bike where it will operate. Don't worry about connecting wires yet.
-Test continuity anywhere on the frame to inside the socket. There will be 2 spots inside the socket where the bulb contacts. One of them will be the earth.
I'll give this a shot tonight and report back.
