Indicators will not flash

[Golfcarmad]

All wired up with correct bulbs and engine running-still no luck

Are you using a 3 or a 2 pin flasher?

[Golfcarmad]

Genuine 3 pin flasher from another 400/4

Only two reason for no flash if all bulbs lit
1 not enough load
2 duff flasher unit

I replaced mine with a 2 pin one.  I think it was about £8.  It does sound like the unit is duff.  You've got the correct load, and they all illuminate.   Csnt very anything else really.

Thanks for advice everyone.
Looks like no indicators for time being.
Take care and stay safe.

Working on the basis of "Any port in a storm", back in the early 1970's I worked part time in a motor accessory shop and we had a home made gizmo for checking customers' flasher units if they thought they were faulty. I checked one unit for a chap and it did not flash, just stayed permanently illuminated. As he was about to purchase a new unit, I went to pass him the old 'duff' one and dropped it on the hard floor. As a laugh I re-tested it and as you can guess it worked perfectly! Just a random thought, and after all, what have you got to lose? Stay Safe, Mick.

Ah yes, the old 'hurling it at the floor' trick

I tried hitting with hammer!!

Hi got the same problem (sort of ) indicators would flash a few times then freeze so put two pin flasher unit on (second hand ) and Indicators work a few times then freeze again . I gave unit a  flick (with finger ) and hey presto they work but for how long I don’t know !

I had something that sounds similar - both the front and rear lights, and the console light would come on, but not flash.

The battery I was testing with was dead (i.e. not holding a charge). For testing my wiring loom I set up a bench power supply at ~13v and magically the indicators started flashing.

I just hope they continue to flash when I get a new battery.

Should do

[Bryanj]

Or have engine running or both

un crimp the unit and carefully remove the internals there is a earth wire from the internal part of the flasher to the alu body of the flasher and there should be a good contact between the alu body and the green terminal. if you look the green teminal on the underside of the insulated board makes contact with the can and it gets very corroded there. Give that bit a good clean. Hope that all makes sense.

Think he sorted it now, turned out to be bulb wattage
