I have a non working horn and wipers. I decided to by pass the cars harness and run switches and relays to power these for now. to get thru inspection.
1- what guage wire needed for wiper motor and what amp fuse? 2- what gauge wire needed for horn and what amp fuse? 3- what gauge wire needed for two radiator fans and what amp fuse? thanks!!! jim Attached thumbnail(s) |

got another fuse block at advance today. a buddy of mine suggested i use 10 gauge wire all the way to my wiper, and horn & radiator fuse block. so i will be swapping out the 14 gauge i used in these segments.
he suggested a 5 amp fuse for my horn, 2 amp for wiper, and a 10 amp for radiators, but he is not a 914 owners, just guessing. |

I'd just fix the factory wiring. I think it was all 16ga, but it's in the wiring diagrams.
I ran 8 ga to the front to a fuse block. Powers 2 fans, headlights, windows and amp so far. 20-30 amp fuses mostly because that's what I had. |

Non working horn and wipers would make me want to check J13 on the fuse panel of the stock set up. It also runs the fresh air blower and in the Haynes manual is called the fresh air blower relay.
If you have modified stock wiring and maybe damaged wiring harnesses from a previous owner and need to go with separate wiring: Your 10 ga. to the fuse block is OK as long as you do not put too much on your new fuse block. Say horn - 5 amps 14 ga. wire OK wipers- probably 5 amps, but try a 7.5 if the 5 blows 14 ga OK Radiators fans - here you need to test them and use an ampmeter to really know what they are drawing. Then double what one needs and add 50%, Say 5 to 7.5 amps each. so 10 or 15 amps times 1.5. A 12 gage wire is good for say 20 amps all day long considering the length of your run ( maybe 10 feet?).

tom - thanks - jim
i know fixing it the RIGHT WAY is best but since i have to run 12V to my radiators the right way, i figured for temporary, i would fix/power my horn and wipers HALF ASSED for now : ) |

Temporary has a way of becoming permanent. You don't want to be a DAPO do you? Fix it right the first time.

It ain't rocket science. It's 45 year old wiring and components, in a 45 year old car, that has suffered through god knows what sort of abuse. If I can use one so can you.

Even a $20 a Harbor Freight special is good enough multimeter for our purposes. You mostly need to see if something has +12V on it or not, and sometimes measure resistance in the ~10-10K ohms range. And the exact values are almost never important for our use.

Yes. Maybe overkill, even. Basically any voltmeter/ohmmeter will work for what we need on our old cars.

Fluke meters are the gold standard. Great to have if you use it often, but overkill for the typical hobbyist.
