I just moved this from the Electrical category, figured Help Me may work better. Sorry to everyone reading this again.:disappoin

Now that I'm driving my 73, I'm trying to help a friend get her 77 280 running. The car is stock, 80,000 miles. The fuel injectors were replaced, and the whole fuel system flushed, last year. New plugs, wires, rotor, cap. The car ran for a while, but they let it sit over the winter, and it won't start up now.

First thing, the fusible links are a total mess. Someone spliced them together with whatever wire they could find, no terminals on the wires, corroded, etc. I know Courtesy sells the fusible links in 3 gauges, in 3 corresponding colors. What are the gauges that I need, and does anyone have a pic of the fusible links installed, so I know which color wires go to which terminal?

Also, the owner tells me that the last time they tried to start it, the mechanic told them they weren't getting any fuel. Of course, this is the same guy who "fixed" the fusible links! Does one of the fusible links control the elec. fuel pump in a 77? I spent the last year learning all about 240's, so I think getting a fuel-injected 280 running will have me on this board a lot once again. Thanks in advance for the help.

Thats perfect webdawg, you the man!

I took the info that webdawg attached, and went to Courtesy to order the new parts. They have the black and red fusible links in stock. They list the black one as 1.25 mm, just like the info webdawg provided says. However, the red wire (which looks like it should be 0.69mm (50 Amps) according to the info) is only 0.30mm at Courtesy. What gives?

Different type of wire used than the original? As long as it's rating is correct it will work.

Courtesy only carries a green link (.50mm - 40 amp), a black link (1.25mm - 80 amps) and a red link (.30mm). They don't carry a link in .69mm (50 amps) which appears to be what 3 of the links are in the 77 according to the info that webdawg posted.

What rating does Courtesy list for the red link?

I just looked the Courtery website and judging from their illustrations, they have the size of the link printed wrong.
