i have a 71' 240z the fuse that controls the dashlights and the side marker light is over heating, as in not breaking the fuse but melting my fuse block instead. we have checked everywhere the only thing we can find is that the dashlight are getting a little juice not enough to turn them on but just a little when the switch is off. has anyone else ran into this problem or if they havent got any suggestions plz help

I think I had a simlar problem with my 'Z' a few years back... Check this thread out and it may solve your problem..

Hate to be the one to say duh.... but what about the Parking light upgrade harness that eliminates the whole problem and gives you brighter lights in the process????

MSA or Motorsport Auto ( www.zcarparts.com ) sell them for about $60. The Harness plugs into the combo switch and introduces a relay into the circuit, eliminating the hi amperage that is killing your fusebox.

I know you're new here so you probably never heard of me or my upgrades. Email me at wolfin32z@yahoo.com and I'll give you links and other info on all the electrical upgrades you'll need to get your Z back in shape and ready for night driving again..

Hey Phil, did ya forget about me already? Don't you have some of my upgrades, and know what they do?

Oh yeah ...... Actually I was just being lazy when I did the post, just did a search on melted fuse boxes and posted the link....

If you put Dave's upgrades head light, and parking light upgrades in instead of having all of the current run through the combo switch, and the fuse block, you re-direct the current through the relay's in the upgrade...

I've installed both of Dave's head light, and parking light upgrades, as well have having him re-condition both combo, and turn signal switch mechanisms.. probably one of the better investments I made in the 'Z' since I owned it.

It's been over a year since I've had the car out on the road... I'm still screwing around installing all of the ignition and distributor crap I brought a few months ago.

Ericster: The Japanese electrical systems designers really went marginal on some of the designs of the electrical circuits in the Datsun. With age the marginal designs do not hold up. Go with Zs-ondabrain has to get rid of the problems and FIX the designs.

Thanks alot guys big help im gonna purchase the upgrade didnt even think about a upgrade thought it was just crossed wires thanks again
