Yes it is all nice and all priced fair, a hard combo to find these days lol.

I wish I had known about these, I have relays all over my car, ,AC heater blower fan, AC compressor, ignition Charging system, low headlights, high headlights,FUEL PUMP,Holley DASH, I thought i was getting quality relays from Bosch when I did these, BUT I now have had 3 relay,Harness failures, looks like I need to change ALL of my relays , Thanks again

if all your relays were 30amp, would going to 40amp along with 10ga inputs help any ? unless of course the item needed larger [60-80amp] ones.
i will be re-wiring a bunch of stuff on my charger using relays, and was figuring a buss bar fed with 4 or 6ga, then to the relays with at least 10ga feed.
however, i was thinking of using bosch style or new mopar style relays. [like found on 2012 and newer vehicles]

I think the larger wire & better relay would fix the issue, I am GUN SHY with the Bosch ones now, as money permits I will change all of them to these https://leashelectronics.com/products/single-70amp-relay-module
& put a fuse size applicable to the application

Charlie....... any chassis dynos near you that you could test the car on without having to make the trek to the track to see if the problem is solved after the relay upgrade?

Great minds think alike mine is just a little slower LOL GREAT idea Dwayne !!! , yes a guy that we used to street race with in the 80's, Bumbera's performance has a Mustang Chassis dyno that I will GLADLY pay them to make some pulls & see what happens, he is about 15 minuets away,, the drive to the track is hard on me so knowing the car is fixed will make the trek a little bit more bearable, as always I will keep y'all in the loop.

Just a note on the leash board that kind of applies to your relay problem. The relays on all of his boards are potted and not removable, you can send them to him and he will change them if they are bad. He said he has seen way way more problems with the connection with the relay and not the relay itself. That is why his boards do not have removable relays, one less thing to worry about.

Thanks for the info, I will just order an extra assembly & keep it in my center console, I drive this car everywhere & it TRULY is a test bed for parts failure LOL, most of the problems I have had would not have happened if it was a RACE car only , things get hot, wiring ,,ect,, Thanks again

I know what you mean, since I drive mine a good amount also anything I do to it has reliability and ease of service behind it. Since I try to do Drag week when I can I always look at things from a "side of the highway" perspective when it comes to repairs. There isn't a whole lot that can take my car down on the road. Two fuel pumps, two fans, spare power circuits, 8 coils etc. But it only has one rear main seal and that is why it had to have its first tow truck ride several months ago
