1967 Fuse Box Question

[Kirk McHugh]

I have a 67 327/300hp convertible with AC, power steering, and power brakes. I was replacing the fuses in my fuse box with the really neat color coded ones I recently purchased. As with all of these things there were some descrepencies in the fuses provided and what was stamped on the fuse box.
My box read:

Bulbs/Gauges 10A
Heater/AC 25A
Radio 10A
Inst Lps 4A
Stop/Tail 20A
Clock/Haz 20A

Which jibes with the Owner's Manual.

The fuses provided read:

Bulbs/Gauges 10A
Heater/AC 10A
Radio 3A
Inst Lps 4A
Stop/Tail 10A
Clock/Haz 20A

The booklet provided says to use a 30A in place of the 25A recommended. What about the 20A for the Stop/Tail? Only one was provided in the kit. Should I get a second kit? Thanks.

Visit the local junk yard and look in any 67+ GM product. You might get lucky and find your correct fuses

Kirk - Not sure where you got the color coded fuses from but unless the suppliers have a newer source than the ones I've seen with thin colored bands on the outside of the glass, they are not similar in configuration to the original fuses that were installed in 1967. The Buss fuses had the color band on the inside of the glass and the original Littelfuse fuses that used a colored "dot" to designate the different amperages.

The list with the fuses as you have it shows a 10A fuse for the heater/AC but it should be 25A (either a white band or dot fuse) for the heater w/o AC and 30A for AC equipped cars.

I would not buy a second kit since the 20A fuse should not be a problem since they were clear, i.e. no colored band or dot, and most parts stores should have the 20A glass fuses.

Re: 1967 Fuse Box Question

Can someone tell me what the correct configuration of colors is for each of the fuses? Thanks.

Re: 1967 Fuse Box Question

Kirk - There was an article in the Restorer several years ago. I can send you a copy if you don't have it. Pete

Peter,

I do not have the article. Please forward. Thanks.

Hi Kirk:

The fuse colors are listed in section 14 of the 67 JG, "Under Dash Area," as follows:

4 Amp: Pink
10 Amp: Red
20 Amp: No Color
25 Amp: White
30 Amp: Gren

To get an idea of what the original color bands on the inside of the glass looked like, check the photo in ebay item 140173456609. The fuses show up frequently on ebay.

I would not recommend installing original fuses in a car that you are just driving, since a slight mishap could destroy one. Original fuses should probably be one of those "judging day only" items. This reminds me, though, that my set of original fuses has been installed since the National in July. I think I'll make a note to remove them.....

Re: 1967 Fuse Box Question

Joe,

I saw that, but I wasn't sure if that was a complete list of colors. Interestingly, I have an original white fuse in my box. I assume that the color stripped ones won't pass judging? Is that correct? Thanks.

Re: 1967 Fuse Box Question

Hi Kirk:

My car, which I believe is equipped the same as yours, has the following fuses in the fuse block:

2 red
2 clear
1 white
1 pink

You can reverse-engineer this because the ampere markings for each fuse are marked on the fuse block, and the color codes are listed in the JG.

There is also a 30 amp fuse under the hood on the left fender, in line with the big red wire. That fuse is hidden inside a fuse holder, so the judges can't look at it anyway.

Regarding your question about how the reproduction fuses judge, I guess it depends on the judge. I would expect a small deduction for the reproductions, at least at the regional or national level.

Re: 1967 Fuse Box Question

Joe - It's interesting that your car has (I'm assuming) a 25 amp (white band) fuse in the HEATER A/C location because C60 Corvettes were to have had the 25 amp fuse replaced as called out in UPC C60, SHEET E1, ITEM 7 with p/n 120114 FUSE which is a 30 amp fuse. Please note that p/n 120114 is for the non-color-coded fuse. Like everything else, we can't assume that the 25 amp fuse was always replaced, but if the fuse was replaced at least on early 67s, it might well have been replaced with a non-color-coded fuse and from my experience that seems to be the case, so I haven't seen many light green color coded fuses in original A/C cars but it's a small sampling base and it's somewhat difficult to get data because I don't like to ask owners if I can remove the fuses to examine them. So, if it an A/C car has a light green fuse on the HEATER A/C spot great but if not, it still could be "typical factory production." Pete

Re: 1967 Fuse Box Question

Hi Pete:

Whatever my car had originally is long since lost to the sands of time. I was just describing to Kirk what I thought was correct, based on the markings of the fuse block. I was not aware of the modification described in the AIM. That is very interesting!

Re: 1967 Fuse Box Question

What do the fuses with the "dots" look like? Is it just a dot of paint on the outside, or inside like the Buse fuses? Just thinking it might be easier to replicate.

Re: 1967 Fuse Box Question

Hi Kirk:

I've never seen the versions with the dots, but maybe Pete Lindahl can describe them.
