I am looking at Delco Remy model 681 low tone. I believe but want to confirm that this is 6 volt before I purchase.
I am also looking at Delco Remy 646 High tone and 645 Low tone but have no information if they are 6 volt or 12 volt.
Is there a reference schedule anywhere that specs the voltage for '50s Delco Remy Horns?
