3C 1000 Starter Relay
« on: September 09, 2019, 02:44 »
Averted a disaster today -- when the Custom 3C we're just finishing building, had the starter relay stick -- when it was fired up for it's first test ride. Some frantic removal of side panels - to pull fuses, and praying it didn't toast the starter --- !! Is there a readily available (parts house USA) alternative to the old OEM one we were using?
Thanks.
Brid.

Disappointingly true >:(

However, Brid has rebuilt the bike to the customer's instructions - his bike, his choice - and it's another Laverda back on the road, so hopefully somebody can give a useful reply to Brid's perfectly reasonable query and suggest a good replacement for the starter relay :-[

An adapted Aprilia RSV starter relay from ebay seems to be flavour of the month.

Pretty much any starter relay will do the job. The original was probably a Bosch, with a mounting tang attached. I believe it was the same as those fitted to VW beetles of the era. Simplest solution would be to go to an auto electrical shop and buy something that'll fit in the space available. I'd suggest you get one rated to at least 100A, but a higher capacity one may last longer.

Alternatively, talk to one of the Laverda parts suppliers. I guess Wolfgang would be your nearest parts man. At least he's on the same continent as you.
Greg Parrish (DAM Laverda) also sells a neat little relay that'll do the job  https://damclassicracing.com.au/71306993-1-starter-relay-12v-dc-with-bracket/

I'm with Cam, try an get a 80-100 Amp relay. Seem to remember that O'Reilly has a good selection of automotive parts in store.

I have used a proper car type solenoid (not a relay as originally fitted) it was super cheap and came from British Leyland, so Land Rover/Austin/Morris etc I fitted it underneath the battery tray as its a bit bigger, it lasted twenty years and then I bought another.
