I've been playing with the Parts List CD to try & identify my starter solenoid, which is the next part for me to check in the quest to get Tara to BL Day.

I think the part number is 13H5952, but I can't see how to translate that to equivalent Lucas parts (which is the numbering that seems to be preferred by eBay listers); am I just being stupid, or is that not covered?

Do you mean this one on fleabay www.ebay.co.uk/itm/AUSTIN-ALLEGRO-MAXI-STARTER-SOLENOID-/220557021806

Make sure the connections match yours

[Richard Howe]

That's the thing; there's 3 & 4 contact versions, both advertised as suitable for Allegros. That one doesn't state which it is, and I'm not 100% which I need as I've not been back to my car yet - ah the perils of having a remote lockup!

What we could do with is some sort of parts number cross-reference guide i.e. BL part no. X = Lucas part no. Y.

I t think there difference is between series 1/2 and series 3. Not sure which is which though.

I did find 2 parts listed in the parts list but it said that the second superseded the first due to it being no longer available.

Right; Tara has a 4-terminal solenoid, which (to be more confusing) has 6 terminals. However, some Allegros have the 3-terminal ones, and I have kindly been offered the purchase of a 3-terminal one at BL day should nothing else be sourced before or at the event.

As far as I can tell, the 4 terminal ones simply have 2 siamesed terminals for different wires where the 3-terminal one has a single terminal. If those wires were connected in another manner, would the 3 terminal solenoids be usable in my car?

providing that what you say about just having siamesed terminals is correct then yes.
early and later minis had 2 types 3 and 4 terminals also, the only difference is, as you've described (that and the price).

The 4S inertia starter solenoid shown will have:

Two large connection points (From the battery and to the starter motor. The battery live terminal usually has additional feeds taken from it)

One 'lucar' blade connector from 'line 50', starter solenoid feed from the ignition switch. Wire colour typically white with a red tracer.

In addition some will have an additional 'lucar' blade connector which becomes 'live' when the solenoid is operated. This is used to feed the ignition coil, bypassing the ballast wire on a 'cold start' coil system. Such a system enhanced the maximum coil output kV for improved cold starting. Such a system was employed on some Allegros - usually S3.

Thus a 'four terminal' solenoid can be used with or without any connection to the fourth terminal.

Ah so it'll only affect my cold start facility? Well that's fine!

Richard,

A little more info.

If your car has a cold start coil fitted the additional wire going to the solenoid will be white with a yellow trace. At the coil + terminal there will be at least two wires, the same white/yellow and normally a pink/white from the ballast (resistance) wire.

The wrong coils are often fitted. (My recent purchase was fitted with an incorrect coil for the ballast system on the car!) If it is a ballast system the coil primary resistance shoud be around 1.5 ohms. If it is an 'ordinary' system the coil primary resistance should be around 3.5 ohms.

Merv.

PS Lets hope for good weather tomorrow!

Thanks for the extra info Merv. I've successfully had her up & running, thanks to Andy & Colin's "bypass" suggestion, and now we just have to hope I can find a suitable replacement
