1800: volvo p1800e 1971 flasher unit

[powen1]

HI Guys,
Can anyone tell me if the Flasher unit on Brookhouse part no B664708 is the correct flasher unit to replace a indicator and Hazard flasher behind hazard switch ? Or do you know of any that are compatible , pics of mine attcahed
Thanks
Paul

Paul;

Many variations exist, and without seeing the PN you are interested in...if (3) terminals are similarly located (and better yet, marked), there is a high probability it is a suitable replacement.

Thanks Ron
The part number I have is the one above 664708
Just to check does the flasher relay just do the flashing and the hazard switch arrangement change the requirement for either signal flashers or hazard Flashers ? i.e the unit just does the flashing depending on requirement by the switch ?
Thanks

Flasher is activated right and left by the stalk. The pull out hazard switch shorts the two sides together.

Great Thanks Derek so its just a flasher unit and as long as it can take the load of 2 or 4 signal lights going it should not matter ?
Can you confirm if the 3 pin unit in brookhouse is the correct one to order B664708?
Please

My parts books are on the HD of my desktop PC which is currently in pieces. Someone else may be able to look it up but try and ring Brookhouse and ask about it. Yours looks to be made by SWF. They can also be Bosch, Hella or now days pretty generic and not expensive.

Thanks Derek Emailed Brookhouse last week :-) trying to see if their was a alternative as they seem to be very busy which is not surprising

Paul;

As Derek mentions, both Directional Indicator flashing AND Emerg Flasher action is controlled by that one Blinker Element on 140 and injected 1800s. I just added the injected 1800 Wiring Diagram Excerpt for Directional Indicators to the tech notes. See: https://www.sw-em.com/Blinker_Relay_..._Injected_1800

Cheers
