Re: Inexistent horn bullet terminal

Hi Remy As Paul mentioned it depends on the wheel fitted. Attached are a couple of pictures that might help. I suspect you are missing the brush contact. This is readily available from the specialist suppliers Part No BHA5041. Alternatively have a look on the internet for an original item. (More cha...

Re: Wipers not parking

Hi Andy A little frustrating but I think you are making progress. I suggest the next step is to remove the plug (Not easy) from the wiper motor and with your tester check you have 12 volts on the Green/pink pin with the ignition switched on. This is the live feed to the parking switch to keeps power...

Re: Ballast Resistor location

Hi Charles There are several solutions to this but as your car looks very original I would suggest the following approach. Replace the existing ignition relay with a Lucas type SRB400 relay. This has the same round 26RA shape as the existing relay. The only issue is that it has a blue body but I thi...

Re: Ballast Resistor location

Hi Charles I don’t own a rubber bumper car so you will definitely will have more first hand knowledge than me. The picture I posted was taken in good faith from a car that was supposedly original so apologies for any misleading information. I always thought the ballast resistor was a pink wire that ...

Re: Wipers not parking

Hi Andy Check the 12volt feed to the wiper motor. This is connected to the park switch inside the wiper motor. When the normal wiper switch is turned off this keeps power to the motor until the wipers park and the park switch contacts open. Pull off the plug from the wiper motor and with the ignitio...

Re: Starter motor plastic cover removal

Hi Dave Hear is a link to the relay you need if you wish to go with my suggestion. https://www.autoelectricsupplies.co.uk/product/172/category/36 To fit, simply replace this relay with the current ignition relay using the picture/pin Nos on top of the relay as a guide. Pin 85 – Black Pin 86 White/Re...

Re: Starter motor plastic cover removal

Hi Charles Please see the attached picture. For some reason this did not go through on my original reply. This relay has 2 separate output terminals (87 and 87b.) They are electrically separated when the relay is not energized so the Red/white wire and White/LG wires would not be connected together....

Re: Starter motor plastic cover removal

mgb relay.docx Hi Dave I agree with Vic, BL seems to have made a bit of a meal of this. You could change the starter relay for one with an extra output terminal 87b. Connect the Red/White wire to 87 run a new white/LG from pin 87b to the coil (or find the existing wire in the loom that goes down to...

Re: Starter motor plastic cover removal

Hi Dave Good news .Sorry if my reply was a bit OTT but there has been so much comment on this forum about problems with the car ignition systems on rubber bumper cars, especially around the 12 volt feed terminal (*)to the coil on the solenoid. (*or lack of a terminal on some of the new starter motor...
