Glad to be of assistance here.  As I mentioned, my under-dash area is no longer stock, so I'd appreciate seeing a copy of your photo, if possible. ...   11-11-2006 01:04 am

VIN # 13349 was merely the last of the Mark I JHs.  Production of the Mark II cars began with VIN # 13350 and continued until they ...   11-09-2006 02:03 am

Frank, Glad you could use the speedo information.  As for the fuel sender, the data I provided to your question via the Jensen Mail List (i.e. circa 30 ...   11-09-2006 01:41 am

With Strombergs, fuel pressure at the carb fuel inlet tee should be 2.5 to 3.5 psi.  IIRC, with Dellortos it should be a bit lower (2.0 to ...   11-02-2006 01:57 am

Someone please correct me if I'm wrong, but I think 'bedded in silastic' means lining the sides and bottom of the recess, into which the ...   10-23-2006 02:25 pm

Dealing with a cold today so pardon me if I'm brief.  Disconnected, the temp gauge should read about 60 ohms across its terminals.  Sender behavior ...   10-23-2006 04:10 am

Good idea.  I'd change the text somewhat, though: 1973 Jensen Healey, a very sporty British roadster built around the high tech Lotus 907 four-cylinder engine and components from many ...   10-18-2006 02:13 am

Well, you might consider trying the new LED bulbs.  Probably not cost effective except for a true daily driver, but the 'cool' factor would be ...   10-09-2006 05:21 am

Unless there's a legal or concours requirement for exact replacement bulbs, you can use US type 1157 for the dual filament bulbs (Lucas 380), and US type 1156 for ...   10-08-2006 09:40 pm

You can use common corrugated cardboard to make patterns for all of the trunk finish panels.  Inexpensive and easy to work with. ...   10-08-2006 04:02 am

That is the vacuum switch, which controls the vacuum applied to the throttle bypass valves.  It's an emissions system, and its purpose is to minimize emissions when the engine ...   10-08-2006 03:58 am

Given  what multiple owners can mess up given 30-plus years, there's no "one size fits all" sort of 'explicit directions' to be had.  (BTW, I found that font almost unreadable.  ...   10-02-2006 04:18 am

It's my recollection that the original size battery is physically quite small and IIRC it has been obsolete or nearly so for quite some time.  Here in ...   09-24-2006 02:47 am

I suppose it might be possible to remove the instrument pod without removing the steering wheel, but at best it would be an awkward maneuver and ...   09-23-2006 05:05 pm

The easiest way to service the gauges is to remove the instrument pod, which is the oval assembly into which all the gauges fit.  This requires removing ...   09-23-2006 04:26 am

You can find a drawing showing the correct vacuum line hookups, excluding the anti-runon system, at  http://www.jensenhealey.com/forums/view_topic.php?id=57&forum_id=4  .  This is based on shop manual figures RM5, RM6, and RM7, as ...   09-18-2006 10:36 pm

I don't have any specific recommendations, as I haven't had to look at one of those epoxies for quite a while.  Thanks for mentioning the fuel resistance, it had slipped ...   09-03-2006 05:56 am

You can try one of the aluminum-filled epoxies.  Once the stuff sets completely, you can smooth it down with the aid of oiled wet-or-dry sandpaper on a glass ...   09-03-2006 04:52 am

Sorry to hear of your misfortune.   Incompetent overpriced "professional" labor is a curse we all have to deal with on occasion.  I think that's perhaps the main ...   09-03-2006 04:42 am

Most likely this is due to a defective alternator.  Occasionally a faulty battery will give the same symptoms (generally, an intermittent cell).  For Delco alternators, this sometimes occurs if the ...   08-29-2006 06:19 pm
