where can I find a sealed 30 amp relay

I am looking for a couple of relays for my project. The current need is for the neutral safety switch on my TKO. I am going to tie it in to the two heavy purple wires. I figure I may also wire in a pair of relays for the headlights. Already have the Spal relay kit for their radiator fans, its nice.

My problem is I can't find a chart or part number with a detailed description as to whether the relay is sealed or not, amp rating, or any other specs for that matter.

Everything I have seen says to use a "sealed 30 amp Bosch relay" or whatever. Try telling that to the dweeb behind the counter at your local parts store.
I would like to find a local source, but I guess I could order relays too, I have had to mail order everything else.

Thanks
Chris

Chris-

This is Coppertop, the electronics guru from Team Chevelle. I'll try to dig up some part numbers for you, but I think I have an idea on exactly what you should get. I do a lot of custom work on my '70 (Chevelle), so I like to build stuff from scratch using top-notch stuff, not the generic crap that the auto parts places sell.

I get a lot of my stuff from Mouser Electronics in Texas. They have NO minimum order. I got some SEALED relays (they are Masu****a--Parent company of Panasonic), with diode suppression across the coil, top quality--that would be the way to go. I'll look for the part number. Price was not bad at all.

Coppertop,
Thanks for the speedy reply. That sounds like what I am looking for, especially if they are available with the diode across the coil (although I have been told it is not needed for what I am doing, anything to prevent voltage spikes and increase the life of the relay is better in my book).

I guess instead of getting multiple different amperage ratings, I could just get a bunch of 45 amp relays or so that would cover each circuit, 2 for the headlights, 1 for the nss, 1 for the fuel pump and so on so that I can keep a spare around and just swap out for the individual relay that goes bad. Just in case.

Thanks
Chris

Re: where can I find a sealed 30 amp relay

Found my old receipt...

Here's the link at Mouser:

Panasonic Automotive Relay

If you buy this, make sure you wire the relay's coil correctly as it has a diode built in, wire it wrong and the relay becomes a dead short! 85 = ground 86 = +12 v relay coil power!

Good prices on 12-volt relays at Parts Express:

Harley uses a sealed 30 amp relay in the starting circuit.

Re: where can I find a sealed 30 amp relay

A sealed relay will have a sealed connector, also. You can find these relays, like the GM 25553347, under the hood of many GM cars.

Re: where can I find a sealed 30 amp relay

napa auto parts has several different amp relays, diode protected ones and plug in pig tails for the wiring

Sometimes it's better to let someone think your an idiot, than to open your mouth and remove all doubt...
