Fast indicators.

[George-S]

Hello all,

My 1979 Beta Coupe has had fast indicator flash on both the left and right sides for a long time I have practically run out of ideas, at one point they did use to work but it was very intermittent.

Symptoms:
When using the indicators the speed is correct initially for 2 flashes then it increases to a very fast rate.
•   Left indicators flash too quickly.  (All left bulbs flash/working )
•   Right indicators flash too quickly. ( All right bulbs flash/working )
•   Hazards switch on they flash at the correct speed.  ( All bulbs flash )
•   With the handbrake applied, the relay & dash light at correct speed.

Things I have tried thus far.
- Installed new bulbs everywhere
- Replaced both rear light circuit boards & cleaned contacts
- Replaced the Hazard light switch & then cleaned the new one.
-Clean the contacts in the Flasher controller, Cleaned the internals with electrical cleaner.
-Replaced all fuses, cleaned contacts on fuse board.
-Replaced the round 8 port ground bloom both left & right sides front & cleaned.
-Cleaned the bulb holders on all indicators.
-Disconnecting the Handbrake sensor made no difference.

I am out of ideas my beta uses the Five pin “Italamec 73338” flasher/control unit rather than a normal three pin relay, Its practically the only thing I haven’t replaced and that’s because they are hard to find and I am not even sure it’s the issue?
Shall I just buy a new flasher controller ?

I know this is quite a common fault on the Beta but just not sure what else to try ..I am also interested to know whether there is a confirmed direct replacement for the 73338 flasher/ Lancia 82352625

Any help is appreciated

Hi George,

Given the work you've done already, I'd change the flasher unit. There may
be a resistor or something thats gone bad.

A very quick search shows 5 pin units available for not very much. You should be
able to match up the pins with a bit of savvy.

Hi Nigel,

Is that the one listed for € 109,95 or have you found a cheaper unit ?

George,

I googled '5 pin flasher unit'. There are many.
Autodoc has a Hella for less than £30. Plenty more for under £20.

At those prices it's worth trying.

Something I've just thought of...as we know, fast flashing is normally
because a 21w bulb has blown. If a wire or a connection in the circuit is
mimicking that scenario i.e. the load is inadequate, it'll produce your symptom.
Having said that, yours starts going quickly after 2 flashes, which makes me
think it's not wiring.
