starting issue

Post by go1dwing » Sun Sep 09, 2018 1:08 pm



I chose the 1800 post area so.....anyway, my 03 1800 off and on sometimes would not start, no clicking, nothing. At times the starter would keep running with key off. Now it fails to start. I replaced A and B relays, checked and cleaned starter/reverse switch. Still will not start. I supplied 12volts directly to the red terminal relays' coil and it starts right up. Nothing new added. So, after all this I wired in a SPST momentary switch and that enables it to run like normal. Where should I look next? All fuses check okay, wires ohm out fine. Any help would be appreciated. I do appreciate the "Posting" advice but mechanical expertise would be very helpful. From what I have read, most of the 1800's from 01 to 07, if not more, are just about identical as far as electrical. I thank you in advance for your response.

If you turn on the key and the radio, does the radio mute when you push the starter button? If not, then there’s an issue with the starter button circuit or the switch itself. If it does mute, then there’s a wiring problem between the starter button switch and the small red connector of the “A” starter relay.

Thanks. That gives me a stating point. Yes, with the key on the radio does mute. That is very good info I would have never known. Thanks again. I am sorry I am not skilled enough to give advice to anyone but I appreciate people like yourself that can offer help to people like me. Let me ask you-is there another relay besides A and B or another component that comes to mind that might be defective?

There are other relays in the starting circuit, but the fact that your add-on switch makes it work, points to a break in the wire coming from the starter button switch and running to the red connector of the A starter relay. This wire runs down to the connectors in the white frame under the right fairing pocket and then on to the relay. On the way, it has a junction where it splits and a branch runs to the audio unit. I would pull the right pocket out and check the connectors for corrosion from rain intrusion from the vent above. It might have just enough connection to make the mute work, but not enough current flow to energize the starter relay. If there’s no corrosion, then the wire is broken somewhere and installing a permanent jumper from the connectors to the relay will be the easiest way to fix it. It’s the yellow/red wire in the largest of the three connectors. Should be pin #13 in the connector(C22).

Valuable information and well written. That speaks well of Goldwingdocs. The A and B relays I replaced probably did not need replacing. $ 12 for the 2 of them- no big deal. Since I already ran a wire(actually 2 wires)to series the add on switch, I will try and spice the mentioned wire from the switch area to the female terminal(red)that goes to the relay. Really, thank you very much.

Update; Your great advice has my GW up and running again. I did not find a faulty wire so I ran a new wire from the front connector to the relay coil wire(Y & R)and it starts using the factory switch. Thanks for your help.
