How To Do the Bosch Relay Mod???
Hi
I did search for the bosch relay mod for my starting problem. I still cant find where I can buy this relay and where to mount it? I did see a wiring diagram. Can anyone help??? BTW, I tried a new starter, a good ignition switch, new battery and good cable and I still have the click click no start symdrome. |

I cant help with your info but was wondering if your new starter was bench tested?

I've heard the neutral safety switch can cause this problem. You should be checking the circuit with a multimeter to see where the voltage drop is.
The relay is a band-aid solution...but an effective one. There's a post a while back by Aredubjay explaining the relay. It shouldn't be difficult to find using the search. |

It is mounted down near the starter motor. Just screw it to the bulkhead, with the wiring going to the starter solenoid. http://www.subaru-svx.net/forum/atta...5&d=1213056302 The wire to terminal 30 can come from the main terminal on the solenoid. The old wire with the spade terminal comes off the solenoid and plugs on to terminal 86. The new wire runs from terminal 87 on the relay to the spade terminal on the solenoid. Terminal 85 is connected to ground. Harvey. |

just curious, what does this do?

All the switches last longer, and the starter works every time.:) Harvey. |

I considered doing this to my silver SVX awhile back, then the problem (which happened only rarely) went away... until a few days ago.
What role does heat play? This only seems to happen to mine on warm days, with a warm engine, after the car has sat for 5-10 minutes. And I don't get a "click," just gurgling from the fuel pump. dcb |

Thanks for the info, the picture explains it clearly.
I need to do this also. |

Re: How To Do the Bosch Relay Mod???
A rise in temperature is exposing a fault, which is introducing resistance within the starting circuit switching, there being several points where this can occur.
A relay having less resistance and therefore drawing less current than the starter contactor solenoid, is not affected to the same extent. However it must be accepted that the fault remains and could deteriorate further, to an extent whereby the relay may not operate. |

Here is another diagram and a photo of the installation.
