Relay ,unsure ...

In my BMW i use one Bosch relay to turn on a multy componnent system so i wanna know if the relay can handle one more item,like an Cyberdyne digital voltmeter gauge.I have 4 amps,one eq,one active crossover,cap charge indicator,capacitor voltmeter (in trunk).The new gauge will go in my glove box so i will know how much juice i have in my Optima RedTop.So that's 8 pieces of equipement,will it be OK,i used my HU remote wire not the power antenna so i'm hopping ...my relay it's also fused.

Thank you

As long as your components don't draw more than 20 amps, test with meter, than you should be fine.

if you use a 40 amp relay which most bosch are and use a 30 amp fuse than your fine even 30-40 amps is a lot for turn ons that need like two.

mecp certification is not always needed. I have it and it has not helped me out at all. my experience out shines it.

Hi,the relay i used it's one of those SPDT (single pole double throw...i think they call it) made by Bosch.I don't know how much all components draw amp wise,but prong # 30 on the relay it's fused with a 5 Amp fuse,should i increase the fuse rating ?,it's never blown yet.

Thank you

Then that means that you’re not currently pulling more than 5 amps from your relay. So you will not have a problem adding a few more devices. My advice to you would be to leave the 5 amp fuse and if it blows when you add the voltage meter than increase the size of the fuse.

Thank you all
