Does anyone have a wiring diagram for a 1986 Plus 4, or know where I can obtain one?

You could try here all available via the efforts of one of your countrymen..(-:

Worth consideration is that not all Morgans are wired as per the diagrams.

Good luck.

There is no specific wiring diagram from the 1986 +4 on the GoMog pages.
I recommend that you try to pick a "close-pick" by starting to look at you fuse box.

If you have a standard Lucas 7FJ fuse box then then your loom will be close to the 1984 diagram

Otherwise the 1987 +4 diagram might be most likely better.

Hope this helps

I've obtained two BlueSea fuse blocks with indepedent circuits and am all set to replace the vintage Lucas fuse blcoks on my 1986 Plus 4. The fuse blocks on my car are mounted in the engine compartment just in front of the tool box receptacle.

The fuses blocks are held in place with machine screws, but they are seized, and I've not been able to remove them. I hunted under the dash on the passenger side and found a couple of nuts which I've removed, that seem to be in about the right place, but the fuse blocks still won't move. Any suggestions? I've thought about grinding off the top of the screws, and this might be my last resort.

I am opening this one up again in the hope there is more information.

I also have a 1986 +4 with the Fiat 1,995cc Lampredi engine, and would like to have a wiring diagram. Having looked a lot, I cannot find anything appropriate.

Also, does anyone know where I can find a manual on the engine and gearbox? I have asked the MMC and await a reply. Fiat owners advise that the Fiat 132 has the closest engine, but they also say do not use a Haynes manual as they have misleading information.

Hi Neil,

A kind Morgan soul sent me to read this thread..in hope I could help you. I only come by here now to trace the advice a car that I have been consulted on. You must have one of the few (122) Fiat Plus 4s produced in the late 1980s. Generally thought of as a fine Morgan variant! 12 were carburetted cars and the rest were fueled by LE-Jetronics Bosch (second MMC EFI models after the optional EFI Plus 8s. However, as so often happened, there were not enough of your variant produced to amass much know-how. In fact. the Factory saved money at the time by office copying an even more sparse Manual than they did normally. The MMC certainly can't help you now, 27 years later! They couldn't help much in 1986. (wry smile)

GoMoG does have the Manual printed for your car. [url=https://www.gomog.com/allmorgan/1986MorganFiatPlus4.pdf][/url]Here it is (clickable). It was sent to GoMoG many years ago due to kind courtesy of a Gunnar Svartholm of Sweden. Many moggers responded a request for Manuals years ago and that index it is one of GoMoG's most popular pages. For the community's sake, I wish people would send more! The missing ones pre-1990...https://www.gomog.com/allmorgan/Hints&HandbooksIndex.html

Unlike most MMC Manuals (and those those printed between 1990ish to 1998) your Manual does NOT contain any electrical diagrams. Anyway, Morgan does not print fuelling system diagrams if that is what you are looking for (???). There are four looms in your car and at best we only get the Morgan wiring sections. I ask this because the lack of wiring diagrams becomes grave (pre-1998) when the items in question are not British. British automobile wire colour coding is brilliant, best in the world. You can find what you need from them, diagrams or not. However, I remember Italy (Fiat) used a more rudimentary and different wire coding system and in 1986. And GoMoG only rarely post fueling system diagrams and then only for the most popular EFIs which I source them outside the Morgan world. Lastly, both L-Jetronics or LE-Jetronics do have very hard to find and super expensive diagnostic code readers..though you can diagnose the entire system with a cheap multi-meter if you have know how.

But all this is moot. A simple statement of what is wrong with your Morgan would elicit more help for you. If you want mine, contact me at GoMoG. Otherwise I am sure someone else here can help.assist.

Thank you Lorne, I hope you come back to read my response. Tou have filled a few gaps on how many of the variant were made.

I already have the manual which is on your website, what I would like is more information on the engine and gearbox, enough for servicing and even an overhaul if needed. It may be that a Fiat 132 manual will be the only way to obtain it.

I will contact you on GoMoG.

I do have an article concerning the engine in the morgan. Containing also literature advice...

e-mail sent.

Thank you, Dr Kiss. A very informative article.
