Vauxhall 2l HPC alternator

[Reiver]

Seems to be the original Motorola 14volt 9rc 7047 and I've seen 9ar 2707g 14 volts in comments...this has 3 blades and a nut connection on the back.  Has anyone found a source or a suitable replacement?

This is available but not sure if he ships to the states.  Alternator - X Flow and VX — Sevens & Classics.

Mine is presently working but is leaking a glue like material from the integral regulator on the backside....

The motorola ID is just the regulator; not the alternator assembly. Typically a foil label on the external regulator that shows the settings.

Domestic applications include the late 70s Mercury Capri (prior to 1979 when the capri and mustang started sharing the same platform/chassis) and 78-80 Ford Fiesta. Look for the three spade terminals in a row plus the battery stud. Replacements have subtle differences in case shape and connection placement.

 

Potting compound tends to leak and run with age and heat.

 

An excellent price no-tariff replacement:  https://www.ebay.com/itm/375528898791?_skw=alternator+13107&itmmeta=01KB532ARSSEMPNYEAWNFDD0TE&hash=item576f4440e7:g:pn0AAOSwi2tmjYKA&itmprp=enc%3AAQAKAAAA8FkggFvd1GGDu0w3yXCmi1d2y9hu20McFWhwFk5DzPxfMn38dIcOheMzMjzvzqvsVmWolrHV52jv%2B1sqJH5Z9MKDhxB5FmJGfBf18MyAd9CfRz08Uy%2B9sdG1J7ME7OjLOjQ%2FGuq%2BwOxY2%2BhjyHHKBek%2FOIz7%2FqFDbsATtPVc9VCydxjNz70WCA708X8u%2BkbxTKhDfCXKSU%2FhCfEs6klY8ntlBhRCwMpAB%2FXhLER8IDn2fX4CB8lz5RMGAUZssuGFXQKZTT3HhkTNOoWms0TkZ5bD6TwrW5UzUhWv51nNutoYi1fevsZeeNeE5xHE7G%2FMtA%3D%3D|tkp%3ABk9SR8qsiaPZZg

Thanks very much....really appreciate the effort you made.  I'm on the hunt .... I know alternators can work in either direction so I'll see if I can find one with the properly oriented fan...or, change it out.

I'll try the one you sent the link to.  It does not have a directional clutch and will work in both directions.... I'll simply replace the fan.

I think it will be ok. Looks like a normal rotation alt fan to me. A ccw fan for a pre-90s application is very rare.

Could be why my original Alternator is leaking...the fan on it is oriented for a CCW rotation.  They will still work in that direction as they pull air thru but not efficiently.  Caterham...parts is parts.

 

I couldn't start the Vaux to check rotation as I'm waiting for a windage tray.... no oil so just looked at the present Alt.
