Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Ugh...check engine light is on

Mine came with the fuse. I've got it installed and it pops through into the cabin right down by the passenger's knees and is hard to see. very unobtrusive.

Well the battery tender to cigarette plug idea has worked flawlessly, I am using a 800ma battery tender in this case, and a slightly discharged battery. It did have a red light initially, so it was doing some charging, and this morning is on the "tending" part of its cycle. No issues! Obviously if I was to have a deeply drained battery I would pull the bonnet, and use my bigger charger connected directly to the battery terminals.

I agree, "tenders" are not battery chargers. They require a well charged battery to do their thing.

If you have a dead or low battery, get a battery charger and get it up to normal and then plug in the tender so it can keep it in ready to go range.

Better still get a smart/multi-stage charger that does both. Once on the lower float voltage it makes no difference how powerful it is - they are designed to be left on long term unattended.

Many also have an auto maintenance mode which kicks in every 14 days or so. This stirs up the electrolyte by temporarily increasing charge voltage, disturbing undesirable stratification due to lack of use and warding off ageing sulphation of plates.

Thats the tender connection, but i have the bonnet off to do a oil change.

My CEL has been intermittently going on for 30-45 min at a time. 800 miles on the car. No overt engine issues, no overt findings (pipes, wiring, etc). At the dealer, everything checks out. Awaiting word from Morgan on trying some things via the computer diagnostics. On this side of the pond, we wait till the next day to hear from Malvern. Otherwise looking at an ECU replacement.

Use a CTEK charger via 12v socket, works great.

ok - dumb question
which is the negative (earth) on the accessory socket, the center or the outer contact. I assume the outer is negative.

Correct the outer is negative, the centre pin positive.

Last trip I took the light went out and stayed out about half way through. I've had a busy few days and haven't taken it out. I'm hoping it's going to stay off. Time will tell.

not nice that sinking feeling when that 'f'ing light comes on!
