Ebay Anderson plug 175amp the dogs danglies and cheap/reliable and always make good contact.
Be aware different amp ratings and also different colours which even if same amp rating I dont think fit each other.
 
Are there issues with the trickle charges and alternators??

Usually you would not charge when on the car as it screws the alternator over, of courses you can disconnect the4e red lead.


Solar panels only give max output when the sun shining bright and strong (mid summer) and is 90deg to the panel, all other times its lower, often much lower which is why on your house roof panels performance is naff if you live north of london with an average angle pitch roof.

No issue with a charger connected to a battery in situ. What's the alternator going to care? The diodes will simply have a slightly higher voltage sitting on their cathode i.e. the alternator output side.

Peak reverse repetitive voltage is going to be a minimum of 50V - and that is repetitive, it would happily see a spike of much higher on a one off situation.

So, trickle charge away.
 
Thanks again for replies.

I have found the section in owners manual ref batteery. Thanks. The reason I am off the road is due to cataracts and I might well have looked in the manual before posting but great difficulty reading. and typing Got my wife to read it. I have connected the solar panel now. However I considered the problem of creating problems in the ecu etc by disconnecting the battery and concluded the solution is to connect a spare 12v battery to the terminals or other suitable place prior to disconnecting original battery and removing for charging. This could be achieved with jump leads or a couple of leads with crocodile clips. the only issue is ensuring continuous 12v to the vehicle. Just ensure one of the terminals is not accidentally knocked off!

Your problem prevention is admirable however the ECU will be fine with the battery being removed, left disconnected and then replaced.

ECU's are a lot sturdier than people give them credit for and one of the key factors they have is a very robust input circuit which can even defend against reverse polarity. Most vehicles with their ignition off will even survive reverse polarity battery connection with no more than a frazzled alternator. The ECU will be fine, I would not ever suggest trying it and I would not say all ECU's are the same but it's a simple mistake to make and the manufacturer does a lot to prevent total loss of ECU and other systems.
