Indicator relay connections needed
Morning All  ,
We are nearing the end of the wiring phase - Hooray 
Last item is to sort indicators, Hazzards work fine (sierra switch) but indicators are running x2 or x3 speed. We have a light green wire connected to
49a on the switch with dark green wires to L & R indicators. (aftermarket switch) Question is - i am presuming we need a flasher unit relay, What
wires go to what? It live to 30, what about 85 , 86 & 87 etc?
Cheers
Daz

Fast flashing usually indicates that you have incorrect bulb wattages installed - have you checked they are all 21W with 5W for the repeaters?

When thinking outside the box doesn't work any more, it's time to build a new box

Yep, all present and correct I am afraid
no repeaters atm, just fronts and rears. there are no spare wires for repeaters so I assume they are not the problem.

You might find that putting the repeaters in circuit will slow down the flashing rate a bit as they are designed for 21+21+5 loading - just connect
them in parallel with the main indicators for a test (you also need them for sva & mot). Failing that I would try another flasher relay before
digging around too much.

Thats the problem I think, We dont have a flasher relay at all (unless its in the hazzard switch). Not worried about SVA or MOT because its purely a
track car - To make matters even more complicated our repeaters are LEDs not bulb driven ones, so that may cause more harm than good atm.

I might be missing something here but how are you getting anything to work without a flasher relay ?
Have a look in my archive and you will find a pinout diagram for the Sierra switches - maybe that will shed some light on the subject.

Are you using Christmas light bulbs ? If you have no flasher relay what is making them flash, is the switch a special? The flasher relay needs a
constant power supply so I doubt it will work if you already have something causing an intermittent current.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

The switch we are using is the bottom one off this page. (green handled One)
http://www.vehicle-wiring-products.co.uk/VWPweb2000/switch-2/switch-2.html
It has 3 terminals marked L, R & 49a
The tiger loom has a light green wire from the loom which we have connected to the 49a and the indicators to L & R
I initially presumed it contained a relay but now I dont think so.
The tiger loom has 2 relays in it, Should I presume one of these is the flasher unit then? - maybe replace it to see if that helps?
Otherwise wire in the repeaters and hope that works?

Unless you have recently been uttering Voodoo incantations you must have a flasher unit in there somewhere - follow the clicking sound  The Sierra
hazard switch is normally combined with the indicator stalk so I presume you have modified in some way.
Sounds like the tiger loom diagram needs a closer look.

Pretty sure that switch does not contain a flasher relay so there must be one in the loom. Usually three wire with the terminals numbered 49 (ignition
live in), 49a ( flashing live out to switch) and 31 (earth). If your indicators flash, front and rear the flasher relay must be there somewhere on the
other end of that green wire. Rapid flash means low wattage. A bulb blown or in your case an earth leak or a low wattage bulb. Physically check the
front bulbs especially if you are using motorbike indicators as some come with 8 or 10 watt bulbs as standard.

Good point - the hazzard switch we are using is rectangular and is from a donor car - as there are 3 others which match, but it cant be off sierra as
its on top of the steering wheel !!!
We are not using the "steering wheel" assembly at all - all switches are located elsewhere
No voodoo yet but its getting close :wink:
Ok, Tonight I will cheak all bulbs and wattages,
Follow the click,
Ascertain all the wires and where they are going,
and wire in repeaters.
I will report back tomorrow and see if we have any success

Ok, by wiring in an extra bulb on each side the problem disappears
Presumably this is due to using bike indicators on the front, Does anyone know where i can get higher rated bulbs for the bike indicators which will
still fit - small glass bulb not large car size?

if you can't find any you can always load it with a resistor
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
