Jump Starting

#1 Post by cybercontroller » Fri Nov 01, 2019 1:11 pm

As the battery has got too low on the Rover 25, I will need to perform a jump start and wanted to check it is a case of jump connecting the jump leads battery to battery. I have heard some cars cannot be jump started easily.

Rovers jump easy, only autos can’t be bumpstarted.

If your car is a later model fitted with the Pektron SCU, It might be better to just charge up the battery. If you have the older Lucas 2 button fob it will be fine.

To protect any ECU’s on the car being jumped, the leads should be connected in order as follows;

DONOR CAR - FAILED CAR
1/ Positive terminal to 2/ positive terminal
3/ Negative terminal to 4/ a good earth point e.g. suspension strut bolts, engine mount
Rover 200 BRM
Rover 214SEI
Rover 75 Connoisseur (launch car)

Thanks for that. As it stays in a garage, I sometimes cannot get there regularly enough to give it a run. I aim for fortnightly but missed this windows by quite a bit and there was not enough power to start. By the time I get there it will probably be completely flat again

I am looking at possibly getting this jump starter from Halfords.

As I may well need it again in the future. Has anyone else used one of these?

It’s a better idea to keep the battery on trickle charge-car batteries don’t like getting to a low state of charge.

Ideally yes, but unfortunately the garage does not have a power supply hence the underlying situation of needing to travel there to get the Rover. I was not able to get there when I intended and had left it too long.

I have a generic equivalent of that, bought out here in Abu Dhabi (where I work), for about 1/3 of that price. It works well, especially on smaller batteries and engines (it's not quite man enough for a 6.2L V8 with twin batteries, but copes easily with a single battery 5.2L V8).

EBay may throw up cheaper equivalent items

If you invest in a jump starter, remember to recharge it after each use, otherwise the internal battery will deteriorate prematurely.

So I got an Imazing1500A Peak jump starter and last Sunday used it to start the Rover.

The leads were not long enough to reach the engine mounting as the negative so I had to use the Battery negative terminal.

After nothing happening due to the battery being totally flat I used the boost button which brought some life back including the alarm going off. Turned that off and attempted to start. It turned over but did not start. Back to nothing again. So another boost and the alarm going off again but this time after turning it off, the start was successful.
I left it connected for a couple of minutes before disconnecting.
Being very conscious of the state of the battery I wanted to try and use as little as possible in the way of electrics but being dark had to use the lights. After a run round the block with no issue I took it for a much longer run. One thing I did see was that the clock display was missing some elements. Gradually during the journey these started to return but it took most of the journey which all in all would have been about an hour and a quarter.

It made me wonder whether this was due to a low battery which was gradually coming back to full charge during the journey or could it just be the weather and temperature conditions?
Again yesterday and today on journeys of between three quarters of an hour and an hour, some of the elements in the display were missing but gradually came back. It has happened sooner each time.
The other ting I have noticed is the heated rear screen seems to only be partially working.

Anyone more knowledgeable than me have thoughts on this?

What are the battery readings on a multimeter with the engine on, off, under load etc? Sounds like a new battery may be in order.

I suspect that may be the case event though not checked the voltages. If it is the cause of the clock not displaying well it is a useful check of battery level.

However, the display lost some elements towards the end of the journey in today after becoming clear quickly after starting. So will continue to monitor. But putting the Rover back in the garage for a week or so which will then be a test when I next go back there.

The clock display problem is almost definitely a coincidence.

The clocks fitted to the 25 and 45 do misbehave as they get older: generally segments will come and go at random! (Mine is stuck permanently at 5:52, so is only accurate twice a day, but that's another fault!)

There is a guy on eBay who will recondition the clock for around £25.

Thanks. That might be useful. Do you have the guy's details?

I haven't used the service myself yet, but I believe a few other people on this forum have.
